I am in favor of keeping the negative turned off for the same reason already stated. You can get some jerk like babyeagle used to be that hates everyone & everything and slams everyone. Once that happens the entire system would be worthless. Just because someone posts a specific number of times does not mean they are helpful or serious posts. On the other hand I do see the risk of over indulgence in positive voting for those you think of as friends and building up their rate, but hey so what? We are here to learn and share so if someone gets a high rate quicker than you think they should or if you don't like there posts, just skip that persons post. be a grown up and use your common sense.
