Twitter: somebody had better be working on a feature that lets me see which followers I have in common with a given user. Is it really hard to implement or something? I need this in order to see whether I should be following someone back or not. It's crucial data.
I know there are third-party sites that do this, but the last time I checked out such a place, it didn't really work. Also, I feel like every other third-party Twitter app thing out there wants my login, to which I say fuck you.
I realize the Twitter people are probably busy just trying to add new servers and keep it from falling over, but if they've got a spare moment, this is what's on my wish list. Pay attention to my needs! Mine!
