Under people's avatars, there are buttons marked "applaud" and "smite" that allow you to approve or disapprove of their post, and a karma meter, which measures the number of times someone has clicked these buttons.
I want it to be removed. The system doesn't work for a board this small. There's no way to tell which particular post was approved or disapproved of, so it doesn't help people who make mistakes to amend their behaviour. There's no incentive for people to use the system, so a majority of good posts are never applauded and it's mostly luck whether you get a +1. This means that if anyone gets negative karma, it's very difficult for them to erase it even if they make lots of good posts.
