FriendLynx helps you find your Facebook friends on Twitter

Also,<p>Even if you just started with names, it would be possible to be slightly smarter than just looking for the individual names.<p>For each name you found, you could scan its immediate social network and see if that contained a match for any of the other names. Putting this together might pull up the whole social graph.<p>Add more networks and publicly available information and I'd expect a name-list could come close to uniquely identifying each name on the list.<p>Project anyone?

The frustrating thing about using an app like this, that lives in the cloud, is that I have to expose my Facebook profile to it to get its services. And who knows what kind of app it will become the future.<p>Essentially, I'd love to find Facebook friends that use Twitter but I never, ever use any Facebook apps, everything about them seems totally dodgy.
