I submitted this, but not because of any upvoting deal~ Some sites, such as Quora, use algorithms to rank submissions and comments. They also avoid anonymity to the most part, so people can notice if there's a conflict of interest with a comment or submission. This probably increases the quality on Quora, though they do have large group biases. I don't know if rewarding "correct" votes like that is such a good idea, since it can just encourage even more manipulative voting, and scare people from submitting controversial content. But taking relationships into account would be probably be a good idea, so if people are just up-voted by one group, their weight would go down. The problem on sites like HackerNews (as opposed to Quora) is regular readers don't normally feel it's worth the bother to go back to the main page and upvote something, so submitters often rely on people who know them to upvote something (which can help Ycombinator startups).
