I'm in two minds personally, part of me thinks that General Discussion should be a place where people can discuss other topics and even get in somewhat heated debates (as long as the debate is about the subject, and NOT about the person who's opinion you disagree with). If that's the case, then post-count doesn't really matter, since some people are natural debaters, others simply ignore posts that get too heated because they don't really want to get into a row-esque situation.
Another part of me thinks that giving people back their E-Peens will stop some of the spamming that takes place in the Freespace General Discussion boards.
Of course, the other option is to completely hide post-counts in posts and only display them in profiles, so people can check their post-counts if they like, but it's not like a badge.
