Who you Follow that does NOT Follow you – after you have checked this interesting info, here is another cool web service that dishes out more interesting Twitter users info.
Qwitter is all about catching Twitter quitters. In simple words, it informs you when someone stops following you on Twitter. It sends you an email, for example:
“… John Gruber (gruber) stopped following you on Twitter after you posted this tweet: What’s the difference between Arial and Helvetica”.
Head over to Qwitter, enter your Twitter username and email address. From now on, Qwitter will send you reminder if someone dare to STOP following you on Twitter.
