I'm surprised there is some negativity about the feature. You can drop comments with a rep point but they're private, so it's not like ebay where somebody can be a dick and tell a lie for the whole world to see. The rep point thing here is throttled so one person can't just jack up +1 or -1 on a person. Like any point system, it all will just average out anyway. Some folks will accumulate gobs of points, no big deal, there will always be somebody with the top score at asteroids, somebody who can solve a math problem faster, some one who can lift more weights, etc.
