I think it changes all the time. There are a lot of posters who have been here for a long time who kinda come and go. Then there are people who come and post a lot and then dissappear. The "popularity" on here varies too much to say who's really popular. Besides, we all get to know different people, and spend more time talking to ones we have more in common with I think - or the ones who happen to be online at the same time we are.
