If you haven’t already, you should check out Topsy, a new search engine powered by tweets on Twitter. As opposed to using brute force and following links like Google and all the other search engines out there, Topsy parses every single tweet for links, and adds them to its database. So instead of giving you just the most relevant results (boring), like Google, Topsy dishes out the sites that the most people are talking about.
Topsy is where Twitter meets Digg, and I think there is nowhere that this site can go but up. It will be interesting to see what happens to it as Twitter becomes more and more widely used to spread websites.
