Just a reminder that you're only assuming that the information that arkades would like to add is even accurate. (No offense to them, I'm sure it is, just pointing out that the process of editing that encyclopedia is burdensome for a reason).
Though I'd point out that unless wikipedia has a team of people whose expertise equals or at least vaguely approximates my own (or that of any expert that might contribute), I have to raise the question of whether that's really what they're filtering, or simply something that superficially looks like accuracy to someone unfamiliar with the material.
It also assumes that the inaccuracy of the current articles is less than the inaccuracy of articles under a hypothetical alternative moderation policy. That might be true, or it might not - chase away enough contributors and you're left with one-sided, stale information. I imagine that's fine for an article on the simpsons, but maybe not great if you're looking up leukemias.
