I wasn't thinking about this regarding YC news's quality. It's remained amazingly stable since I've been using it. I was thinking about this regarding Reddit, and how the signal to noise ration seems to be degrading even more recently. The main reddit is fairly unusable for me now, although I like the science and programming sub-reddits. I was asking for ideas for future reference regarding sites with social components. It seems to be a common problem online: how to avoid the troll issue and signal to noise degradation issue. I was thinking that votes could be weighted based on length of stay, or karma or both. Users who've been around longer and who had higher karma are obviously more invested in the site than hoards of users that just started. @PG: I really hadn't thought of weighting everyone's votes similar to the editors. A nice, elegant solution I think.
