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.”

Platforms and products is one of four new operating units created in this latest restructuring, which also birthed an advanced technology group, a marketing group and a consumer group. Why this particular arrangement is any better than AMD’s reorg of a year ago–which spawned the Central Engineering Organization and Computing Solutions Group–is anyone’s guess. AMD CEO Dirk Meyer says it will optimize AMD’s operations and drive the company toward sustained profitability and long-term success. But then he said that about the last one as well.

Oh, speaking of that last reorg, Randy Allen, the 24-year AMD veteran who figured so prominently in the company, is leaving. AMD (AMD) offered no explanation for his departure and there’s no word yet on where he’s headed. That said, some surmise that he may be following a path beaten by two of his former colleagues, Raja Koduri and Bob Drebin, who both fled AMD for Apple (AAPL)
