Hiro should implement a system for /vip/ that lets the users vote on other posters' posts depending on how relevant they think they are to the discussion.
This would improve the quality of discussions significantly and result in productive conversations, in which both sides of an argument are represented.

Comments would be sorted by most votes, users would get points tied to their names/trips which will reveal their Contribution points (CP) to other users, this encourages quality discussion since it would lead to a higher amount of Contribution points next to your name.
Comments which score below a certain threshold of CP will be hidden and reported to the mods.
