According to sources close to the situation, longtime Yahoo front page chief Liz Lufkin has parted ways with the company.

The departure last week appears to be related to a reorg by newish editor-in-chief Jai Singh, who used to run the editorial efforts for the Huffington Post, at the Silicon Valley Internet giant.

Singh appears to be setting up his own team and, thus, Lufkin was out.

Lufkin has been at Yahoo for many years, most recently as VP of front page programming. In that job, according to one bio, she supervised “editors in Sunnyvale, Santa Monica, New York and Dallas and consult[ed] to various international Yahoo! sites. Liz’s group contributed to the successful development of Yahoo’s pioneering content optimization personalization system, improving the relevancy of Front Page for users and providing new insights on audience behavior.”

Previous to Yahoo, she had been deputy managing editor at Gannett’s USATODAY.com and USA Today. She had a similar job at the Hearst-owned San Francisco Chronicle.

Lufkin’s job at Yahoo is a critical one, given how powerful the front page of the site is, with 600 million unique visitors and billions of page views.

While the portal system has been under siege in recent years, it is still a massive driver of traffic to Yahoo’s own Web properties and elsewhere on the Internet.

Yahoo declined to comment (but I am right!).

UPDATE: Yahoo said that it had hired CNET editor-in-chief Scott Ard to take Lufkin’s place. Ard, who worked for the CBS-owned tech news property for 12 years, will report directly to Jai Singh, editor-in-chief of the Yahoo Media Network.

Yahoo is on a bit of a hiring spree, picking up longtime Internet exec Robertson Barrett (pictured here), to run its critical and powerful Yahoo News and Finance sites.

Barrett has held top positions at Tribune Interactive, Time Inc., ABC News, Primedia’s Channel One Interactive and The Feedroom.

Barrett worked most recently as chief strategy officer of Perfect Market, a Comcast-backed start-up.

Last week, Yahoo announced that Jai Singh will join the company as editor in chief. Before that Ken Fuchs was tapped as VP of Sports, Games and Entertainment.

For the huge Yahoo News job, Barrett replaces Mark Walker, who left for Disney a month ago. Steve Schultz left the top Yahoo Finance job last fall.

Here is Yahoo’s official press release, which confirms it and the particulars:

Yahoo! Names Robertson Barrett Vice President of News and Finance

Media Industry Vet to Oversee Company’s Category-Leading Properties

Yahoo! today announced that Robertson Barrett will join the company as Vice President of News and Finance. Based in Santa Monica, Calif., Barrett starts May 16, and will report to Mickie Rosen, senior vice president of the Yahoo! Media Network.

A media industry veteran, Barrett brings more than 20 years experience leading online ventures and as a reporter, including senior positions at Tribune Interactive, Time Inc., ABC News, Primedia’s Channel One Interactive, and The Feedroom. His appointment is the latest addition to the Yahoo! Media Network leadership team, which recently announced that Jai Singh will join the company as Editor-in-Chief, and Ken Fuchs as Vice President of Sports, Games and Entertainment.

Barrett will oversee Yahoo! News and Yahoo! Finance in the U.S., two of the company’s most renowned properties. In the U.S., the Yahoo! News Network is No. 1 in the general news category, attracting 86.6 million unique users in March 2011 and Yahoo! Finance has been the top finance destination for 39 straight months, attracting 42.6 million users in March 2011–more than twice as many unique visitors as the No. 2 destination Dow Jones & Company (comScore).

“Rob’s addition to our leadership team comes at a pivotal time for Yahoo! News and Yahoo! Finance, especially in light of the global and economic events driving massive consumer interest and engagement,’ said Rosen. “We have ambitious plans for these properties, and Rob will play a critical role in leading these businesses and deepening Yahoo!’s position as the premier digital media company.”

Barrett’s appointment comes on the heels of the largest traffic week in the history of Yahoo! News. Following the death of Osama bin Laden, Yahoo! News has experienced its heaviest-trafficked week, including 3 of its top 10 most visited days ever. Since the news broke, Yahoo! News has served more than 865 million pageviews, attracting more than 20.4 million unique users on Monday, May 2 and 17.6 million unique users on Tuesday, May 3 in the U.S. Yahoo! reaches more than 680 million users globally each month.

Barrett most recently served as Chief Strategy Officer of Perfect Market, a Comcast-backed venture, where he was responsible for building relationships with major news brands for the organization. Previously, he was EVP of Tribune Interactive, where he managed the operations and strategic development of online properties in 40 U.S. markets, including latimes.com, chicagotribute.com, baltimoresun.com, and all Tribune news, entertainment and TV sites. He also was previously VP and GM of The FeedRoom Inc., an Internet news venture backed by NBC, where he oversaw the development of video-on-demand for NBC, Tribune Company, CBS and local station groups. He was also co-founder and operating lead at online ventures for Time Inc., ABC News and Primedia’s Channel One Interactive. He holds a BA from Duke University and a Masters from Harvard University.

According to sources close to the situation, Yahoo has grabbed one of Huffington Post’s top editors, Jai Singh, to become its editor-in chief.

The move is a big one in the online editorial arena. Before moving to the HuffPo as managing editor in 2009, which is now the key content unit of AOL, Singh ran CNET Networks.

UPDATE: Yahoo confirmed the hiring in a press release below.

A Huffington Post spokesman said:

“This is about geography–Jai made clear his desire to move back to California, where his family is located. He moved from California to work with us and, unfortunately, this job requires his being in the newsroom in New York. We loved working with him, wish him well with his new job, and look forward to staying in touch.”

Sources said Yahoo sent out an internal memo earlier tonight outlining the move, which is a whole new role at Yahoo. It’s below–natch!–from Yahoo Media head Mickie Rosen.

Hi Americas!

As we discussed at last week’s All Hands, we will continue to strengthen and grow Yahoo!’s position as the premier digital media company by expanding our original content, bringing unique voice to each property, turning Yahoo! into the place for big events, and helping to drive best-in-class tools and practices in social, SEO and publishing tools and operations.

In just the past few days since we were together, we set new records with our coverage of the Royal Wedding. And with last night’s news of Osama bin Laden’s death, we will likely create new ones. This proves the point that consumers turn to Yahoo! to be entertained and informed. We are the place consumers turn to when news happens.

With this context, I am thrilled to announce that Jai Singh will be joining Yahoo! as the Editor-in-Chief of the Yahoo! Media Network. Jai joins from AOL, where he was managing editor of the Huffington Post Media Group, responsible for the day-to-day editorial operations of all AOL content.

Prior to AOL, Jai was the Managing Editor of the Huffington Post where he developed its voice, doubled its number of vertical sections, and helped grow unique users by six-fold. Prior to the Huffington Post, Jai created CNET News.com in 1996, which quickly became a leading authority in technology news. As the editor-in-chief and senior vice president, he was in charge of all editorial and built a news staff that won scores of national journalism awards.

Jai will start May 31st. Below is the press release announcing his appointment.

Go Yahoo!

Best,

Mickie

And here’s the official press release about Singh, which is oddly buried in news of Yahoo’s performance in its Royal Wedding coverage:

Yahoo! Sets Records With The Royal Wedding;
Drives Largest Traffic Day for Single Event

Names Jai Singh Editor-in-Chief of Yahoo! Media Network

SUNNYVALE, Calif., May 2, 2011–Yahoo! Inc. drove its largest traffic numbers for a single event last week when the world turned to the company for coverage of the Royal Wedding. Over a 24-hour period on Friday, April 29, 2011, Yahoo! drove more traffic and video to its coverage of the wedding than any previous event.

Preliminary internal data shows that Yahoo! sites serving Royal Wedding content drove 400 million page views on Friday, slightly higher than the traffic levels experienced following the Japan earthquake. Yahoo! delivered Royal Wedding content at a record-breaking 50,000 requests per second on Friday, seven times the average daily peak of approximately 7,500, and video traffic was 21% higher than the previous record. In comparison, there were approximately 33,000 requests-per-second following the Japan earthquake and today, at press time, peak requests-per-second was 40,000 for content related to the death of Osama bin Laden. Yahoo! also drove approximately 30 million unique users, 27 million video streams and 2.6 million live video streams over the 24-hour period on Friday.

In the last three months, coverage of the Royal Wedding and the Academy Awards has demonstrated that Yahoo! is where global consumers come to be entertained with rich content no other online company offers. Similarly, when news breaks, Yahoo! is the world’s trusted source for in-depth coverage, from the ongoing crisis in Japan to the death of Osama bin Laden. Yahoo! is the number one online site, reaching 180 million unique users and maintains a portfolio of 10 number one sites in the U.S., including Yahoo! News, Yahoo! Sports, Yahoo! Finance, omg!, Yahoo! Shopping, Yahoo! Real Estate and Yahoo! TV (data: comScore March 2011). Yahoo! attracts more than 680 million users globally.

In effort to extend and accelerate the company’s leadership positions and further develop a unique and distinct voice across its brands, Yahoo! today announced that it has appointed Jai Singh, editor-in-chief for the Yahoo! Media Network.

As editor-in-chief, Singh will help transform the company as it increases its original content creation, build the unique voice and programming of Yahoo!’s leading properties, and help drive best-in-class tools and practices–such as publishing platforms, aggressive social and SEO distribution–and programming across all platforms. Singh will be a key member of the Yahoo! Media Network leadership team led by Mickie Rosen, senior vice president of Yahoo! Media Network. Based in Sunnyvale, Calif., Singh starts May 31 and will be spending significant time with editorial teams based in Santa Monica, Calif., and New York City.

“Jai’s appointment comes on the heels of one of the most event-filled news weeks in Yahoo! history, which underscores the importance of our editorial operations,” said Rosen. “Jai is one of the most advanced and respected editorial thinkers in digital media today, and a great addition to our editorial bench strength. It’s clear that when news breaks, the world turns to Yahoo!. Shaping our unique voice, and establishing industry best practices for the next generation of publishing will further Yahoo!’s success as the premier digital media company.”

Singh was most recently managing editor of the Huffington Post Media Group where he was in charge of all day-to-day news management and editorial operations. His responsibilities spanned across both Huffington Post editorial as well as AOL, including AOL content sites. In the two years Singh was at the Huffington Post, the site saw unprecedented growth–the number of sections more than doubled to 24, as did the number of editorial staff, and unique visitors grew nearly six fold, according to Comscore. Besides running the editorial operations, Singh helped drive product development in close partnership with the technology team. Singh was also the main point-of-contact and worked closely with Sales, Sales Development and Business Development.

Prior to the Huffington Post, Singh created CNET News.com in 1996, which quickly became a leading authority in technology news at the height of the Internet boom. At CNET.com, as the editor-in-chief and senior vice president, Singh was in charge of all editorial, including news and product reviews, as well as product development. Singh built a news staff that won scores of national journalism awards at atime when mainstream media were still skeptical of the Internet as a source of credible information.

Brand new MySpace CEO Owen Van Natta started things off Monday with his first day on the job. He was joined by new COO and former AOL exec Mike Jones and new chief product officer and former Sling Media exec Jason Hirschhorn. Down in Los Angeles at the AlwaysOn OnHollywood conference, Boomtown ran smack into Huff Post mastermind Arianna Huffington, who extolled the virtues and abilities of new managing editor Jai Singh, former editor-in-chief of CNET Networks. At AOL, in preparation for spinning off the Time Warner (TWX) Online unit, new CEO Tim Armstrong began appointing new senior execs and spinning off existing ones. Platform-A president and former Yahoo (YHOO) sales exec Greg Coleman, who joined the AOL team in February, is leaving the company, to be replaced by Jeff Levick, who is leaving Google (GOOG)–where he had a close relationship with Armstrong. CFO Nisha Kumar is also leaving AOL, and a search is underway for her replacement. MediaMemo has more on Time Warner’s decision to spin off AOL. A number of Flickr engineers were laid off Wednesday, but Chief Architect Cal Henderson has left the company of his own accord and is working on a stealth start-up with Flickr co-founder Stewart Butterfield. Last, but not least, one of the voices covering the digital scene has found a new gig. Owen Thomas, self-described “scourge of [Silicon] Valley,” is leaving Valleywag to head up GE (GE) unit NBC Universal’s new “Bay Area” Web site, whose motto is “Locals Only.” He’ll be replaced by fresh-faced Ryan Tate, recently the night editor for Gawker. Both reporters talked to BoomTown on Friday about the changes.

MediaMemo wrote on Monday about Condé Nast shutting down Portfolio–both the print magazine and the accompanying Web site. On a cautionary note, MM outlined the reasons why Portfolio’s business magazine peers should not celebrate the loss of a competitor, even (or especially) during tough economic times. Is the meteoric ascension of Twitter flattening out? According to a Nielsen Online study, 60 percent of Twitter’s users leave after a month. This was met with a lot of skepticism so Nielsen ran the numbers again with the same results–and this time it’s sticking with them. MediaMemo also had an explanation for why the long-awaited deal between Disney (DIS) and Hulu took months and months and millions of dollars to finally come together. Digital Daily had more on that story.

Digital Daily also had more info on the ever-evolving Palm (PALM) Pre story. First, a rumor that Palm plans to launch the handset on June 7–which would be crazy, given the fact that June 8 is both the first day of Apple’s (AAPL) Worldwide Developers Conference and the day that those in the know expect the next-generation iPhone to drop. Then, there’s an assertion by Collins Stewart analyst Ashok Kumar based on supply chain research that Palm has greatly reduced its production numbers. Time will have to tell, though, because Palm certainly isn’t talking yet. Of course, things could be worse. Dell (DELL) hasn’t even solidified plans for its rumored smartphone, and already, no one really cares.

Dell’s new Adamo laptop and Studio One 19 desktop aren’t causing much excitement either. In this week’s Personal Technology column, Walt Mossberg reports that although both machines look good and function well, neither is groundbreaking. In Mossberg’s Mailbox, Walt answered readers’ questions about improving performance on a PC, using peripheral devices with an iPhone and installing Apple’s OS X on a Windows machine. And in this week’s Mossberg Solution, Katie Boehret tested three apps from the iTunes App Store that make it possible for the iPod touch to function like an iPhone.

More next week.

She was there to give a speech called “Video Killed the Radio Star…But Can the Web Actually Save Journalism?”

Her answer was a decided yes, especially with great journalists working online, such as the new managing editor of the Huffington Post, whom the mega-blog has just hired.

That would be former CNET Networks Editor-in-Chief Jai Singh (pictured here), who quit the tech news and reviews company last year after a dozen-year run.

“The bottom line is the Huffington Post has figured out how new media should be…and that’s what attracted and appealed to me,” said Singh in an interview today.

While only on the job for a few days, he noted that he will be looking at more video on the site, as well as focusing on its new vertical strategy.

Singh is moving from San Francisco to New York, where the Huffington Post HQ is located. (Huffington herself is, ironically, located in L.A., doing her work out of her Brentwood abode.)

Singh has been a true online news pioneer, creating News.com for CNET in 1996. CNET is now owned by CBS (CBS).

Here’s my video interview with Huffington, talking about Singh’s appointment and the future of the news business:
