I usually like to post in threads that have a moderate amount of posts, or low amount. When it is a HUGE amount of posts and is about an arguement or something, I don't want to get involved, because I would have to read the entire thing, or else the people will be like "Person X said "BLAH BLAH" in post "X" why are you stupid". I usually just look at the title, and if I can post something constructive, I look inside.
