I joined Twitter when we were all desperately worried about Greatnan. Since that sad time I've followed various Tweeters, among them a lot of very local bloggers who write entertainingly about the immediate area, (most Tweets are very short and simply link to longer articles) a few quirky posters - a chap who posts pictures of gates for example, a few friends, some political sites and some religious and theological ones too. I also follow TfL for information and one or two journalists who write about matters of concern to me. It's amazing what interesting texts one discovers, but all too easy to spend too much time on there
