Recently I've found twitter to be a drag because I'm following way too many people.
I want to start following less people so I'm writing a web app that will tell you who tweets the most out of the people you follow.
I'd have it finished but I was going around in circles trying to solve a problem that I just realized I don't really need to solve yet.
I keep thinking of other features I could add, such as who retweets the most and who talks to other people I follow the most which doesn't help.
