If you put a libertarian on a board with a liberal and a conservative, it would inherently be biased towards a libertarian viewpoint. You'd have to get a populist to balance the libertarian, but we don't have any populists here (I think most populists are idiots and can't afford internet connections). It's like playing paper rock scissors, except scissors beats all.
Ideally I think you'd want to or four people who balance each other on most issues. So maybe you'd put me with SM (LOLOLOLOLOL). But that would mean we'd mostly have to exclude libertarians, because pretty much everyone agrees with libertarians on some things and there aren't really any anti-libertarians.
