Track your twitter unfollowers with who.unfollowed.me
Do I really care who decided not to follow me on Twitter? Not really. I'm not hung up on numbers. I just hope that some people find me interesting and/or useful.
I often add people to my lists and unfollow them so that I can read them by topic and not have my home page constantly bombarded with 100+ tweets that don't make any sense in the order presented. So, if I show up as an unfollower to your account, it doesn't mean I'm not reading your tweets. It probably means that you're getting lost in my shuffle and I'm trying make you more accessible.
