Know the difference in your Twitter contact list from within Google Reader

If you have been thinking of writing a small utility which does a difference in your follower list based on predefined Twitter Time Synchronization,there is a good news.
You don't have to write this application yourself.I reviewed it yesterday and I was fairly impressed by the results unlike Qwitter.

I followed the following steps:
1) Created an account with http://twitdiff.appspot.com/splash (Basically giving Twitter OAuth permissions)
2)Consumed the RSS feed after setup in Google Reader (reader.google.com), which is my general purpose web content reader.
3)This morning I opened Google Reader habitually & my twitdiff feed was also updated here
