Products on a list to be sunsetted–whatever that means–include MyBlogLog, Yahoo! Picks, AltaVista, Yahoo! Bookmarks, Yahoo! Buzz and Delicious. Some of those properties came from acquisitions and others were internally generated.

The news of the Yahoo plans first came out via a screenshot of the Webcast posted on Twitter by Eric Marcoullier that included a slide with a list of impacted products next to an image of Irving, along with EVP of the Americas Ross Levinsohn, announcing the news.

Marcoullier was founder of MyBlogLog, which created one of the products being shut down. (MyBlogLog was bought by Yahoo in 2007 and has been pretty much neglected ever since.)

The slide also shows plans to merge additional products, including Fire Eagle and Yahoo People Search, and make features out of many others, including Yahoo! Alerts and Yahoo! Calendar. (If you have better eyes than I do, please help identify some of those logos in the comments.)

Marcoullier is no longer at Yahoo, although the validity of his Webcast screenshot was confirmed, after he was quickly criticized on Twitter by various current Yahoo employees who didn’t appreciate it getting out, including Irving himself, who insinuated he would fire whoever leaked the Webcast.

While the layoffs and shutdowns obviously indicate a de-emphasis of technology products by Yahoo, they aren’t necessarily unwarranted. Some of these products were the same as those mentioned on then-SVP Brad Garlinghouse’s infamous Peanut Butter Memo way back in 2006 as candidates for streamlining.

Update 12:21 p.m. PT: Yahoo’s statement on the matter just came through:

Part of our organizational streamlining involves cutting our investment in underperforming or off-strategy products to put better focus on our core strengths and fund new innovation in the next year and beyond. We continuously evaluate and prioritize our portfolio of products and services, and do plan to shut down some products in the coming months such as Yahoo! Buzz, our Traffic APIs, and others. We will communicate specific plans when appropriate.

In response to a follow-up question about Delicious, which seems to be the “sunsetted” product people are most upset about, the spokeswoman replied:

“We continue to operate Delicious today, and will communicate specific details when appropriate.”

In a bit of coincidental timing, said Gnip CEO Jud Valeski, the filing for the round was posted yesterday on the SEC site (which is where I found it). He confirmed the round amount as $2 million, coming mostly from previous investor Foundry Group and including First Round Capital again. This brings the company to $6.6 million raised so far.

Gnip’s deal with Twitter finally brings pricing clarity to usage of Twitter’s data streams, at least for analytics and monitoring companies. The company has permission to collect significant revenue on the streams. Previously, Twitter’s only paid data option was the Firehose full stream of all user status messages, for which it charged different amounts depending on the size of the customer and what it was doing with the data. While Microsoft paid $10 million to incorporate the Firehose into its real-time search, some start-ups that create Twitter clients were getting the Firehose for free.

As I reported yesterday, Gnip will offer social media monitoring companies the Halfhose (50 percent of Tweets at a cost of $30,000 per month), the Decahose (10 percent of Tweets for $5,000 per month) and the Mentionhose (all mentions of a user including @replies and re-Tweets for $20,000 per month), with the caveat that they can’t publicly display the data.

Boulder, Colo.-based Gnip has gone through a big turnaround in the last year. In September ’09, it laid off seven of its 12-person staff, saying the huge increase in creation of social media data had overwhelmed the company’s self-built database and it needed to start over. In May of this year CEO Eric Marcoullier left the company, leaving it in the hands of his co-founder Valeski. Marcoullier, who had previously founded IGN and MyBlogLog, is now working on another start-up, the “Foursquare for Web sites” OneTrueFan.

But a deal with Twitter–a company that has historically expanded into its developers’ territory much to their dismay, rather than blessing third-party companies with partnerships–is a firm indication that Gnip is back on track.
