I know, I've already dished out seven of my favorite Twitter tips, but I've got a new one that is sure to come in handy if you want to know what's hot on Twitter.
What Twitt(url)y does is track the most talked about URLs on Twitter and displays the 100 most popular URLs from the past 24 hours. Similar to Digg, users can vote for a URL by sending a link to their followers on Twitter.
Considering the fact that we're all realizing the power of using Twitter as a search engine, I'm sure a ton more sites like this will be popping up in the near future. Oh, and if you are searching for something specific on Twitter, there's always Twitter Search too.
