I'm coming round to the new system. The old system just required volume regardless of quality, and that was part of the spamming problem. The new system involves ( in part ) voting on post quality by the posters peers. If this is not abused, then it could be a great way to improve quality. Part of this is as a result of a type of feedback on posts. If I make a post that is seen to be helpful, and thus gains some merit points, then that appreciation encourages me to make further constructive posts. If a series of posts don't receive any merit points, then I know that I am on the wrong tack.
