It depends on the thread. Some threads are so long, I cannot keep up with them. Especially the diary ones. I'll peek at them once in a while, but that's about it. Can't sit and read all of them or I'd be here forever.
I just can the topics, I don't go to Recent Topics, I just hit every topic and whatever thread is highlited, I'll check out if it interests me.
Sometimes it looks like I live on the board, but in all actuality, I forget to close the window at times. lol
