Good point. In general, it would be good to have a more thorough process for exploring difficult-to-anticipate side effects before new features are broadly released -- something there's been a lot of discussion about lately.

Back to Ryan's original topic -- the sometimes inappropriate nature of discussions on Commons -- I started a draft of an essay (which, at least theoretically, could eventually become a guideline if there is enough support for it). I think it might be a decent start, but it could use more input and fleshing out. Please take a look, and feel free to edit as you see fit:
