With the recent adoption of voting systems in forums (like this one) we are seeing troll comments often buried, and this will perhaps continue to discourage that behavior. On a bigger note, articles that draw clicks with bold conclusions or headlines (like that nerd baiting article we saw on Gizmodo) are still grabbing eyeball share and thus will continue to propagate instead of real news/information. How that fight for eyeballs is resolved is one that I don't really see a solution to yet.
