Try social bookmarking site: http://ma.gnolia.com/

from their About screen...

"At Ma.gnolia, members save websites as bookmarks, just like in their browser. Except with a twist: they also “tag” them, assigning labels that make them easy to find again. So when you search for something, you use words that people choose and look only at websites that people think are worth saving. Suddenly you have access to a human-organized bookmark collection that numbers in the millions, but is as easy to use as a search engine."
