Yup. A high quality open list can stay that way only if participants
are willing to take the time to discourage those who make low quality
posts. This can be via a moderator, flaming, careful critiques,
obscure language, an appearance of boring topics, or whatever. Of
course some of these techniques are more "civilized" than others.
