I don't use lists on birbsite. I tried a few times, but I always forget that they exist. Or, when I used tweetdeck, didn't like having so many columns. And adding people to lists, how do you ever remember to do that. And it's so much work. I am fascinated by people who manage to use lists, but I guess they're just not for me. I'd be grateful if people didn't suggest lists when I complain about following too many people. They're… not a solution for me at all. :s
