BoomTown provided continuing coverage of the Yahoo (YHOO) merry-go-round. This time, PR head Jill Nash announced her departure. As the company’s chief communications officer, she’s had a challenging two-year run. New CEO Carol Bartz definitely has some PR ideas of her own, including offering cash prizes to employees who provide info on their colleagues who leak information to the press. Not a huge deterrent yet, apparently–it didn’t take long for BoomTown to get info on both Nash’s farewell memo and Bartz’s bounty system. Next, New Networks, the publisher behind BarelyPolitical and its hugely viral Obama Girl videos, has widened its purview to include the tech sector with BarelyDigital, which the online network has envisioned to include regular shows, tech news remixes and the like. It’s rumored that Obama Girl will be making a cameo appearance or two. If the first two features are any indication, the future looks pretty funny. In another round of executive musical chairs, Time Warner’s (TWX) AOL ad head Lynda Clarizio will be leaving the online service, to be replaced by former Yahoo ad exec Greg Coleman. Microsoft (MSFT) is launching a slick new celebrity site on MSN called Wonderwall, created, designed and produced by BermanBraun Interactive, a Hollywood company run by former Yahoo media chief Lloyd Braun. And speaking of musical chairs, MSN is clearly upping its content ante–earlier this week, it hired Yahoo’s recent media head Scott Moore, who used to work at Microsoft.

MediaMemo asked: What happens when one of the world’s richest men lets loose a swarm (a small swarm) of mosquitoes at a high-end conference? Nothing too exciting, really, but when you consider that the stunt was the publicity-generating part of Bill Gates’s talk at TED, which was a discussion of malaria and some of the problems the Bill and Melinda Gates Foundation is facing head-on, it gets pretty compelling. Kindle 2.0, the new generation of the device dubbed the “iPod of the book world” will be unveiled Monday at a New York press event, but how many of the devices have been sold thus far? Amazon’s (AMZN) not telling, but Citigroup analyst Mark Mahaney estimates the number at 500,000–and believes that the Kindle will be a $1.2 billion business next year. Obviously, a lot will depend on Monday and the new device’s reception. MediaMemo also took some time out this week to wish Facebook a happy fifth birthday, and to stack its track record next to Google’s at the same age, with interesting results. Even the pros are getting hit hard these days–in its quarterly earnings report this week, News Corp. (NWS) missed its estimates, recorded an $8.4 billion write-off and lowered its guidance. CEO Rupert Murdoch admitted that the downturn is worse than he thought. He also admitted that he spent $2.8 billion too much for Dow Jones. (News Corp. is the owner of Dow Jones and this Web site.)

Digital Daily followed the trial of four Google executives this week on criminal charges of defamation and breach of privacy after a much-publicized two-year investigation. Google (GOOG) insists the charges are unwarranted and “akin to prosecuting mail service employees for hate speech letters sent in the post.” Clearly, the ultimate outcome will have a huge impact on the future of a free, open Internet. MySpace said this week that it has identified and ousted 90,000 registered sex offenders–and those are just the ones brilliant enough to use their real names. There’s no way of knowing how many are actually using the service or how to prevent them from re-registering once they’re deleted. A free an open Internet, indeed. DD also pondered the future (or lack thereof) of the Motorola (MOT) handset division. Co-CEO Sanjay Jha says the company is committed to making the business work, but its products are looking boring and outdated, and a turnaround would be prohibitively expensive to execute. In the words of one analyst, the company’s problems are “gruesome.” On the other end of the spectrum, Microsoft continues to vehemently deny reports that it’ll be producing its own smartphone. In a report this week, analysts from Broadpoint.AmTech speculated that the device could be uncrated later this month at the Mobile World Congress in Barcelona. Meanwhile, it’s been up in the air for two years whether or not iPhones will ever be uncrated in historic Georgetown. Apple (AAPL) has been around the table a few times now with preservationists wary of the architectural impact of an Apple store, no matter how much the business traffic is needed in the neighborhood. Looks like perseverance may have finally paid off, though–Georgetown’s Apple store could open later this year.

In Personal Technology this week, Walt Mossberg took a look at a program called Foxmarks, which sets out to synchronize bookmarks among all of your browsers and all of your machines. Sound a little too handy to actually work well? Walt found it does a pretty good job, with a few caveats. In Mossberg’s Mailbox, Walt responds to readers who want to know more about doing “techie” maintenance on their PCs to keep them running well, whether or not to buy a 15-inch MacBook Pro, and options for email within Windows 7, which won’t ship with a built-in email program. In the Mossberg Solution, Katherine Boehret tests Google Latitude, an opt-in program that lets users track one another’s movements on their smartphones using GPS, Wi-Fi, and cell towers. Kind of like Gawker Stalker, only with permission and without Lindsay Lohan (unless you happen to be Lindsay Lohan).

Last but not least, Silicon Valley lost one of its own this week. The widely admired and much loved Mike Homer, whose rare, severe illness was a rallying point for many over the past months, passed away last weekend and was laid to rest on Thursday.

More next week.

In an interesting and innovative move compared to what has typically been less-than-hip online programming over the years, Microsoft’s MSN service is debuting a slick new celebrity site called Wonderwall today–created, designed and produced by a Hollywood company run by former Yahoo media chief and well-known television exec Lloyd Braun.

Using an unusual horizontal design with a scrolling “wall,” a plethora of pictures and a deeply visual sensibility, it’s definitely a laudable risk for Microsoft as the company seeks to continue to push itself into the online content business, despite a lackluster record.

The site, by BermanBraun Interactive, which is being launched right before the Grammy Awards, will aggregate content from a variety of partners, but also use a small staff of editors to differentiate it and give it “voice.” BermanBraun will operate Wonderwall for MSN.

Last week, in yet another sign that it is upping the content ante at MSN, Microsoft hired Yahoo’s most recent media head Scott Moore, who used to work at Microsoft (MSFT).

“We are investing more than ever in content,” said MSN GM Rob Bennett. “With Wonderwall, we are creating an offering to attract and retain new audiences, using content that is already at the core of MSN.”

But unlike other MSN sites, there is more subtle MSN branding on Wonderwall, although Microsoft’s search will be an important part of the site. MSN will promote Wonderwall across the service and will also give it an external marketing push.

To make money, Microsoft and BermanBraun are jointly selling the advertising for Wonderwall, which also has a partnership with MediaVest, to bring major brands to the site.

One obstacle is the huge amount of competition in the Internet space, from AOL-backed TMZ to Perez Hilton to omg! from Yahoo (YHOO), which is currently the most-trafficked celebrity site (and, ironically, was pushed through Yahoo by Braun and Moore).

But the interest in this pop culture category is obvious–celeb-focused online programming has grown strongly.

Celeb news-obsessed BoomTown accounts for much of that traffic (How much do we love following the hijinks of Britney? Much!).

So, I hightailed it to the Santa Monica offices of BermanBraun yesterday to have a look-see at Wonderwall and do some video interviews.

Overall, I was struck by the site’s arresting visual design, particularly the easily interactive wall, which has what I can only call an “iPhone” feel combined with a flipping-through-a-magazine tone (see above; click on image to make it larger).

With more touchscreen technology moving to personal computers, you can easily see Wonderwall being manipulated by hand.

And it makes great use of linking out, another plus, without excessively pointing to only Microsoft sites.

One problem: No true ability for users to interact on Wonderwall, via comments or other social-networking tools, which Braun said are coming soon, along with videos being able to be played in the main wall.

But overall, it raises the stakes in the celeb market and gives users a new interface without straying too far.

Here’s my video interview with Braun, along with another below it with his partner, former Fox and Paramount exec Gail Berman, and also Wonderwall’s top creators–all talking about Wonderwall.

(And, as an added bonus at the bottom, Oasis singing their hit, “Wonderwall.”)
