6.58
It was around 8.6, then I went through a phase where I didn't give a shit about other people's feelings at all. It went down.
I started voicing my own opinions (not in an obnoxious offensive unbased way as far as I know) and obviously it went down. Every thread that I post an opinion that can be taken in more than one way, the karma drops.
If I help someone it doesn't often go up, so I know that the system is definitely off a little. People seem to find it easier to "punish" someone for disagreeing than "reward" them for being a good member. Like giving karma for posting porn passwords? Or for having a funny icon? Or a funny name? Not worthy of karma in my opinion, but in others' eyes that's all that matters.
So basically what I'm getting at is that each person's karma rating isn't really reflective of who the person is or how good a person they are, so it shouldn't be something that people care about. Just something to be noted to know how people on NS think.
