It's apparently agreed that we need a "back it up" style expectation of quality but support for actually placing it in the FAQ was very meh.
The general suggestion so far has been to gauge expertise by reputation and use up/downvotes to confirm the validity of posts...but honestly that hasn't been working. People pile on the same exact answer and get upvotes. People state the obvious and get upvotes. People contribute nothing of worth to the question but get "I agree with this" upvotes.
In order for this site to be useful it's very important that answers are more than just noise/piling on, and that upvotes mean more than "Sure, I agree with that".
How can we enforce a quality standard for answers if we're against putting it in the FAQ? I'm not seeing this unspoken quality standard being enforced through voting at all and I'm rarely seeing it enforced via comments on answers.
