I know I know, comments 99.9% of the time are non-constructive; but goddam it, I enjoy reading them. Sometimes they're good, but most of the time just a laugh. I like you're attempt to try something new (old) but as others have said, I don't do social media other than Twitter which is just too restrictive for decent comments. Its ironic though that I'm using HackerNews to comment on this. I'm a big fan of building a community who can self-police comments. It may be a pipe dream to be full proof that a bad comment will be down voted enough to remove it completely, but I really think there's a better way than resorting to email and social media.
