Qwitter

There is a site called Qwitter where you can log in with your twitter log in details and you can find out who has stopped following you on twitter.

It's a shame they don't have a facebook equivalent, though it's normally perfectly obvious who has removed you from their friend list seen as they don't appear in your list anymore!!

There have been a lot of articles talking about how Qwitter could cause fall outs and hurt feelings but it's a cyber world, it's not real in-fact in the real life it would be good to be able to quit people as easy as it is in the online world. Believe me, I'd have done with some people ages ago hehehe. Who wouldn't!
