What The Buzz! was a Google Buzz report generator. You gave it a username, and it extracted some funny data about that user's Google Buzz usage! Google cruelly discontinued Buzz, so the service was shut down... But you can still see an example here!
Personally, I liked WTB a lot. During the time that WTB was active, more than 600,000 different profiles were seen and more than 8,000,000 requests were processed!
I don't know why the buzz Google discontinued this service, it was a heartbreak for me :D.
What The Buzz! was written in Python, too.
