No, something that high is good, or there could be a lot of people karma-ing.
This might be too hard to do, but maybe you can only become a karma-er if 50% or so of your +karmas are from mods, otherwise friends could boost each other up, sock puppets, etc.
Also, in the member list, we should be able to list by post, location, join date, etc, like we did before, and also list by karma, so people can instantly see who is helpful and who is not. (Or rather who is liked by the community and who is not.)
