She confirmed that social news site Buzz and Yahoo's Traffic APIs will be shut down, but didn't comment about other services listed on the slide as slated for closure, including Delicious and the geolocation tool Fire Eagle.

Delicious is emblematic of the Web 2.0 services that jump-started innovation on the Web after the dot-com bust, by popularizing community participation through content tagging, sharing, mashups and collaboration, along with Flickr, Wikipedia and Blogger.

Delicious was founded in 2003 and acquired by Yahoo in 2005. Its founder, Joshua Schachter, left Yahoo in 2008, worked at Google and is now an angel investor in technology companies.
