Scroll to the bottom of this press release about the Yahoo!-Tumblr deal.

Yahoo! still has sharing buttons for del.icio.us, (a product it hasn't owned since 2011 and has been known as "Delicious" since 2007), Digg (which relaunched last year and doesn't let you add details to submitted links anymore), and Yahoo! Buzz (which no longer exists).
