None of the categories or threads that interest me are recently active, and I've read other members' posts already. Sometimes I search for other inactive threads that interest me to post in, but sometimes I'll just carry on with other things. As of the time of this post, recently, I go here at least twice a day, and usually post at least once each time, usually three or so posts each time, but I still occasionally forgo posting.
With me its all about time. I have to keep my activity up to stay in WOM but at the same time I really do like reading what people say and the questions they ask because its things I haven't given much though too but wish I could!
