Re: What's the point?
For all those who recently joined and don't have many rep points yet:
It takes time. That was one of the purposes of this system. We didn't want somebody to join one week and have 400 reputation points the next. So if you feel that you aren't getting anywhere with your rep, please be patient and keep posting.
What if this wasn't a rhetorical question?
All models are wrong. Some of them are useful.
