TweetEffect – find out when people followed or left you on Twitter

I’ve just finished uploading and fixing TweetEffect a web app that allows you to check which of your latest http://twitter.com updates resulted in people following or leaving you:

With the demise of Qwitter there was no real update mechanism to know when you lost followers, this might be a step to fill this gap. TweetEffect does not tell you who left you, only the number of people. The reason is the draconic rate limiting of Twitter. This is also the reason why the app largely runs in JavaScript and only does checks server-side when you provide a user ID on the URL. This allows for bookmarking and sharing with others.

Check out some examples:

• My Twitter Updates
• TechCrunch
• BBC

What do you think? Anything else to add?
