Thanks for the thoughtful response @taskmaster4450. I think you hit it on the head when you say that we may have a flood of trolls and negative people join the site, but I imagine they will quickly lose interest because they will not be able to get very far. The beauty of good content being rewarded, is that those quality members of the community also contain the power to set the direction of the culture with their votes. Of course, if we get a bunch of trolls that are filthy rich and have a lot of power, then maybe that would be different. I imagine that is a small minority though!
