I can't help but like the spirit of the vouch system, and I'm sure quite a bit of thought went into it. But at the same time I'm wondering if the site really needs two different versions of up-vote/down-vote with different different semantics.
Still, I get it, it's a kind of super-vote, reserved for people with a little karma (i.e. some "skin in the game"). Out of curiosity, how'd you guys arrive at 30 for cutoff?
