I had a strange experience over a month ago; I lost 90+ twitter followers in just a single day. I twitter about it the same day, however I have yet to know what made that happen and don’t even remember which followers were unfollowed. If I had known of the service called Qwitter back then, I would have had a better idea of when and who unfollowed me.
Quitter emails you every time any follower of yours decides to unfollow you on Twitter. This may be useless for Twitter users who have hundred and thousands of followers, but for small users like me who have only a hundred or a few hundred followers – this is a valuable service. Now you can finally know what your followers are doing.
