I'm not 100% on the Rep thing either. It seems to me to be a little game the regulars play, kind of a popularity contest. You get good rep points for posting something someone else agrees with / appreciates. You get bad rep points (I guess points taken away) if you **** someone off or make a knucklehead statement. I've gotten rep points once, mostly the regulars have let me say what's on my mind but I'm very conservative.
