A leaked pic of the internal slideshow from a Yahoo! "all hands" meeting earlier this week listed several products to be "sunsetted" including: Delicous and AltaVista. Yahoo! confirms that Yahoo Buzz will be closed, as will the Traffic APIs. Delicious seems likely to go, too.
Here's the statement from Yahoo!:
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.
