HN is the only very large, threaded comment forum I know of that is still (a) anonymous, and (b) actually has excellent content in the comments. In my own opinion, the signal/noise ratio is nearly 2 orders of magnitude greater than places like reddit (or perhaps the mathematically correct formulation is that the noise/signal ratio is nearly 2 orders of magnitude less at HN). I credit the excellent, thoughtful moderators at HN for that.
