Another nice Twitter tool that has popped up is Qwitter. What it does is it check your followers and notifies you of people who have stopped following you on Twitter. The service checks as often as possible but with a large amount of friends and followers it all depends. You will get an email letter you know whats good, as well as a link in every email to remove yourself from the Qwitter service. All you need to do for sign up is enter your email address, and your Twitter user name. Then your good to go, the service will do everything else for you. Again, just another little tool for anyone trying to build a power account over at Twitter. These two will defiantly help you.
