I’ve heard about this karma system but what’s the point of it? How does it benefit me? Can someone answer this?
Sure. When you place in the TOP 3 each week you will get a forum badge saying you are an answerhub sage. But, and maybe even more importantly, you help others learn the system. Other than that, nothing else…

i really hope UE team can give something better than that so people will have better motivation to answer others questions , something like if you have higher karma then you will get answer quicker than lower one or some prize .
well, if they make the answer depend on the karma, its probably something wrong with the answerhub. i thought the questions were answered as soon as somebody knows the solution.
i think its better to keep it as self satisfaction, other than a race of who has more points.
Today I received a bad karma and I don’t know why :C… My motivation go down because I feel I’m doing the things well…
I was almost to reach 200 points 
Don’t worry and take a look at this answer, probably one question reopened.
