I read it and it was a good comment, but I think it's a mistake to assume that this can be sustained in the event that the site really does take off. Such a stable environment is possible in a small online community but less so in a larger one. I'm not suggesting you should penalize users for behavior they haven't yet engaged in but I do think it's important to be aware of the danger that there are always going to be people who derive enjoyment from gaming the mechanism of any website they join.
