An insightful vote is worth 2 points, a funny vote is worth 1 point. So for example, 4 insightful and 4 funny is 8+4=12 karma points.
This new scoring method applies to both comments and posts. There is no way to remove karma, it's a 2-upvote system. If you want to report content to be removed, use the 'report' button.
Have fun and feel free to let us know if you see any bugs or if you have ideas for improvements!
