I've decided to take on a liberal policy of following people back on Twitter. I look at this way: if you think you want to listen to me go on and on about stuff, then I figure I should return the favor. It's just being nice. However, I don't just blindly follow everyone back. I get requests to Digg and Stumble stuff and generally if I don't think it's something I would honestly Stumble or Digg, then I won't. And if I take a look at somebody's Twitter and don't think I would consider following them if they hadn't followed me first, then I just don't.
