It might be interesting to see a system that allowed a maximum number of posts per day to newcomers. People could vote on each post, if they want to see more or less of that author, topic, whatever. Then people's posting quota could be adjusted accordingly. If there were no size limits, people could still squeeze all their stuff into one post per day. It would just be easier to skip. If they were popular and widely received, they would have more posts per day. As flame wars erupted, people could squash the flamer's posting rights by popular consensus.
