While I'm certainly not one to turn down an opportunity for points, I have mixed feelings about this one. I too moderate point submissions and have for quite some time now, but have always thought of it as a way to give back to the community since I was able to witness a pretty explosive growth with just a handful (I think at the time, 2 or 3) people moderating all those points. So I asked David about the process, volunteered to help and was shown the ropes and have quietly been going about it here and there since then.
Perhaps a measure of rewards might be something as simple as another badge in the forums, or perhaps a set amount of points rather than having it go based on how many submissions you approve. Just my thoughts as a fellow moderator! :)
