The Twitter Economy: Qwitter
Qwitter is my first entry to the Twitter Economy, the expanded world around Twitter.
What’s Qwitter anyway
As their motto says it, it’s about “Catching Twitter Quitters”: a simple tool that automatically sends you an e-mail update whenever one of your followers un-follows you.
The email recevied not only tells you who quit on you, but also after what tweet (or Twitter entry, if you prefer).
Useful?
Personaly, I love it and use it on all my Twitter accounts. It’s evidently limited by the fact that people can quit on you for various reasons and not especially that last entry you added. Still, it allows you to track 
unfollowers. You might be able to detect trends if you alter the way you micro-blog or if your brand made changes that seem unnapproved by the community.
A tracking tool is better than no tool at all. You could even parse the result in a database to create trend graphs.
Business model
Contrast.ie, the company behind it, launched Qwitter in October 2008. It seems that it is a pet project to play along the Twitter API and to offer users a nifty tool. There’s not declared intent on monetization, either as a pay-to-use model or ad model. The only possible hint at their future plans?
Qwitter is not affiliated with Twitter, but wouldn’t it be cool if it was?
It’s on the main page …
