This might be pretty old, but I just discovered it. It looks like Google is looking to bring twitter users together through their Follow Finder. The way the site works is that it analyzes the people that you are currently following to find others that are following the same people as well as people who you might find interesting.
The results were pretty good, although most of the people that came up for me were people that I was already following.
If you'd like to follow me. You can find me @8thlight.
Thanks for stopping by,
