It's not nice to care about people unfollowing you. Twitter is used by many as a stream of news, so it's a natural process that my interests shifts over time I want to unfollow people twitting about stuff that are no longer pertinent to what I'm doing right now.
Don't like these kind of scripts. They are like "Yyz read your away message" or even worse "Xyz closed your message window" in ICQ and other messangers.<p>But nice code.
It'd be a little easier to do this by requesting followers/ids (<a href="http://apiwiki.twitter.com/Twitter-REST-API-Method%3A-followers%C2%A0ids" rel="nofollow">http://apiwiki.twitter.com/Twitter-REST-API-Method%3A-follow...</a> ) if you have over 100 followers. That'll give you 5,000 id's at a shot and then you can just do a simple diff of id's.<p>Yes, you'd have to then request their profile info so {1:6, other:0.5*dozen}.
You can get an rss feed of unfollowers: <a href="http://rssfriends.com/only/unfollowers/yourusernamehere" rel="nofollow">http://rssfriends.com/only/unfollowers/yourusernamehere</a> (eg <a href="http://rssfriends.com/only/unfollowers/oliverg" rel="nofollow">http://rssfriends.com/only/unfollowers/oliverg</a>) -- it's an undocumented url: and at first, setup this site to track your username by entering it on the homepage
