We all know how much fun it is when we log into our favorite email app and have several new emails waiting for us from Twitter, proudly announcing “______ is now following you on Twitter.” Some people live for this (those on a quest for Twitter followers as if there were a prize to be won), while others could care less and simply go about their digital lives.

For those that follow their follower numbers more closely, Qwitter is a great tool for tracking those users that drop off your Twitter stream. Over the past few months the service had been down (for reasons unknown to me), but just recently I started getting emails from them again, which is good news (even though they deliver bad news).

The premise of Qwitter is that just as Twitter will tell you when new users start following you, Qwitter will tell you when they stop. It’s notification email mirrors Twitter’s almost identically, though it also pulls in your most recent tweet, trying to illustrate what scared the user off. However, just because that was your most recent tweet does not necessarily mean it was the thing that tipped the user off, so don’t let it bother you too much. You could have been cut for any reason.

Warren Sukernek (@warrenss) wrote a great post on Qwitter back in December and had some great links to others who ranted or raved about the tool, but for me its not much to get worked up over. I use it because I like to follow the ups and downs of my followers. I won’t go out of my way to interrogate unfollowees or question their loyalty, as its none of my business (unless they care to share).

If you want to track your Qwitters, give this tool a try. If not, you can save yourself the trouble of trying one more Twitter app.
