User comments and discussions on the internet have a pretty bad rep these days, to the point where many people have just opted out of online commentary completely, going as far as using a combination of DNS filtering and browser extensions to remove them entirely from their browsing experience. I, on the other hand, have spent the last couple of years refining ways to separate signal from noise in the cacophony of online user commentary, as I have come to believe that the most valuable knowledge I acquire on a daily basis comes from commentary and discussion rather than publishing.
