I have a love/hate relationship with Twitter lists. They help me filter people that I follow but they don’t really mean much. I can’t get any stat data from them so it’s not as useful as they could be. And I don’t really follow that many lists because I could essentially do the same plus it’s there’s effort click that isn’t really worth the time. However with all that mentioned there’s one list that I think you should check out if you’re into bitmap or ascii art. @daniel_rehn has put together a list of those that are making Twitter-art. There’s all sorts of experimental digital stuff being streamed in via Twitter.
