I realized the current system works pretty damn well when I thought "I wish these were points were visible!" upon seeing a heavily up-voted comment of mine. I quickly realized that this is a really bad concern to have when commenting. There is such a fine but significant difference between getting feedback that let's you know people like what you say, and publicly displaying it. The former is the natural desire to be right/smart/insightful, the latter is actually the desire to appear right/smart/insightful to others.

I think we've all seen this pattern of fame at any scale: Smart but unnoticed person finally gets attention for their work, people notice this and the person appears smart and worth listening to, after time the person's focus shifts from the smart work they did to work maintaining the reputation of being smart.

I think it's great to get some form of acknowledgment that your ideas are generating positive feedback, this encourage thoughtful comments and provides a real reward to those primitive parts of our brain that want to be the big monkey. But any further and the big monkey starts to be the one doing the talking.
