I find it quite worrying that people will rely on Wikipedia but stop editing it because it's hard and because not everyone is friendly there. Yes, part of the time that you spend editing Wikipedia is lost because you have to look up obscure conventions and templates and policies, and argue with people every now and then, including some rare cases where it's hard to assume good faith. You should be fair though -- Wikipedia is a huge endeavor, and administrative friction is unavoidable to some extent.

If people stop contributing, though, the bureaucrats will take over, and we cannot afford to let Wikipedia stagnate and die in this way. It's tempting to leave the administrative burden to someone else, but it will get heavier and heavier for those who stay.
