This week's Tuesday Thingers question is about online discussion groups - specifically, how many do you belong to and do you actually participate. I belong to 8 or 9 on LibraryThing, and a whole bunch on YahooGroups. I started in the the Yahoo group world when I was in college years ago, and had unlimited time to spend reading group emails. I can't remember the last time I checked those groups, or that email address. I participate somewhat regularly on 3 groups on LT - Battlestar Galactica, Early Reviewers, and the Green Dragon. I am not online every day, so sometimes miss out on discussions I might have participated in, but in general I find the LT groups to be a lot of fun!
