No... Some of us do, but I still get in my measure of sleep. There's a lot of topics I find to comment on where I can make a positive comment, such as when helping out others or replying to something someone else said and keping the flow of conversation going.
Other times, it's just crazy posts where we get involved in the game we're playing. And of course, there's all the fanfics to review.
Hope this helps give you a general idea... Just keep having a good time here at MC, that's the main thing.
