As I puruse the internet I have come across a ton of different search engines. There are the big ones like the omnipresent (and perhaps omniscient) Google, and yahoo isn't too far behind. The ones I find interesting are some of the more specific searchers like skreemr for mp3s. I recently found the coolest specific search engine ever though, it is called please dress me and it is a T-shirt search engine. I saw it linked from Boing Boing and it is worth taking for a whirl.
