Stars and titles are just something that all message boards have, most message boards have titles for the post count.
I can see the argument from both sides, the titles could be misleading but people like to "achive" something from posting. I think the best solution for something like this is to bring the system back but change the titles associated with them. At 5000 posts a person shouldn't be called a Expert. I know on one of the boards I'm on at a certian post count people got to choose their own names. Personally I don't care one way or the other, yea it's cool to get diffrent titles for post count but it isn't going to make me post more or less one way or the other.
