Gataga is a search engine that allows you to search using tags across multiple sites that use tags.
Right now, it searches: del.icio.us, flickr, technorati, blogmarks, blinklist,jots, spurl, furl, podcast, simpy, connotea.
That list is an eye-opener all by itself.

Yes, I’ve noticed them up and down a little. It’s there now, earthlings.
