Why not start your own similar message board? I'm not just being glib. You know HN is based reddit's free software, right? I would love to see more competition and more variants of moderation policies. I've watched reddit's and slashdot's both evolve in interesting ways. I've run phpBB forums and ended them quickly b/c of the load of moderating. I've been on usenet groups with extremely high signal to noise ratio. I've got many more ideas on how to solve the problem of optimizing signal to noise, so I know many more people must have them. I say, GO FOR IT!
