I've been pessimistic about such things since the beginning of always - no clue where it came from right now anyway. But if people can behave with the new toy, that would be quite nice.
Ditto, i don't see of any good coming from it.
If people are helpfull, you'll know pretty soon, if they arn't, you'll find out.
All this karma thing screams is for someone to find a way to mess with it and give someone -10000000 karma.
I don't like the post system either, it promotes spam.
I sincerely feel both should be removed, they add a macho component, increase problems, and just cause stress.
Please feel free to show me the positives of such things.
