I think furthering the discussion in this case means talking about the pros and cons of adding a comment length requirement. Since the site owner pg is in on this thread, the community may benefit by Paul getting some feedback and ideas on how to improve the site. The site's design does encourage conversation of course. Comments are threaded to encourage back-and-forth, and voting moderation promotes good comments and helps to keep the discussion civil. I too like to get some karma, but I'll sometimes write something that I suspect may be down-voted (or even that I may not believe) just because I like to discuss things. Karma doesn't really matter on this site or affect your experience (other than being able to down-vote comments), and I think that fact encourages people not to treat it very seriously.
