Hmm, Google's core competence is search. As many commenters pointed out yesterday (in the big "Yahoo shutting down Delicious" thread), Delicious is more than a place where people store their bookmarks; it can be used as a kind of alternative search engine as well. So I think it wouldn't be a bad fit. Also, Google has been trying to get "social" right, and this could be a part of the puzzle.
