Site of the Day-Gataga

Gataga is a unique search engine that searches only del.icio.us, blogmarks, blinklist, jots, spurl, furl, simpy and connotea. All of these sites are either social bookmark hubs, RSS feeds, or both. Gataga's look is similar to Google's in that it's very simple and easy to use: all you need to do is enter in a few tags (same thing as keywords) and Gataga will attempt to match your search queries with something from its database.
