Edelman launched Tweetlevel today, a Twitter measurement tool to find out who the most influential people on Twitter are. In other words, now when @comcastcares sees someone complaining about their cable service being out, they know whether or not they have to respond. We kid.

The tool is in beta, but the initial results are revealing: Hollywood blogger Perez Hilton is the most influential person on Twitter. PRNewser scored a 42.

To be fair, on the site's "About" page reads the following statement: "Even though we believe that it goes a great way to understand and quantify the varying importance of different people's usage of Twitter, by no means whatsoever do we believe we have fully solved the 'influence' problem."
