I think the standard should be in the name. I only upvote here, if something makes me think or makes me learn something. This can include fiction, art or fun.
I just checked the "new" column and felt weird about random sportstalk (strategy or analysis would be fine) or random recipes.
Languages will selfmoderate in the longrun. I'd love a german community, but I don't think it's profitable to post in german. So I say, let other languages stand. It's tough enough, since they have such a niche amount of potential readers.
RE: So do we have any sort of standards or is proofofbrain a total free for all? also downvotes...
