who.unfollowed.me - tracking

"Do you ever wonder the age old question, who unfollowed me on twitter? Wonder no more! We allow you to easily check your unfollowers on your schedule, every 15 minutes, without waiting for an email or a direct message."

A very simple tool that tracks those who unfollowed you on Twitter (but not why, you need to work that out)

Probably more useful for Brands/ Celebrities rather than individuals - but will you stay aligned to your core values and loose followers or abandon your values and go for volume.
