Overlapr
Dan Benjamin, my friend and co-host of the currently on hiatus Tack Sharp, has been cooking things up in his mad scientist laboratory in the hidden submarine that he keeps off the coast of Florida. Earlier this week, he released Overlapr, a tool that tells you how many friends and followers two Twitter users have in common.
For example, who know that half of the people that follow me also follow @gruber?
Certainly, if you're trying to divine the meaning of life based on follower and friend overlaps, then this is definitely a tool to help you out in your pursuit of that. But, what’s interesting to me is what Dan might do next now that he’s playing with social graphs. For example, take the overlap of people that Dan and Gruber are following and then compare them to my following list. Maybe there’s a recommendation engine in there... or maybe not. Who knows.

I recently launched Tweeteorites (http://tweeteorites.com/), which has a recommendation engine along those lines (the "Should Follow" pages). It also takes into account favoriting activity among all of your friends.

Interesting timing, Eric Meyer just launched sort of the exact same thing: http://meyerweb.com/eric/thoughts/2009/07/06/announcing-followerlap/
(NB: I do not want to imply anything with this, it's more of a 'great minds' thing) Fun to play with anyway.

Maybe it's just a case of a 1.0 release, but doesn't it seem like it should tell you who you overlap with?
Fun site and it is pretty. I'll be curious to see where it goes.
Despite my feature complaint, good for Dan for keeping it simple. Many Twitter "add-ons" seem to go a little overboard feature wise rather than making them actually usable.
