At Folklore or official policy?, I wrote, "I feel like I've come into the movie theater in the middle of the movie. Please, help me understand what's going on in this site and what is expected of me."
Highlighting some material from that thread:
We write stuff in comments that is too obvious to qualify for an answer. [Such-and-so] is not really a topic for a site for linguists and etymologists, and we don't want it to become a topic.
As for formal or official policies, it seems to me Stack Exchange has a relative lack of them.
The closest thing to formal policies that I know of are the documentation in the Help Center, and the mechanics of the site itself.
SE etiquette is that meta questions are about an issue, not a user, so names are usually left out of questions on meta to avoid making it about a particular user.
Also, today I read
this site has a policy of not discussing poetry
I'd like to assume that the goal is not to set up a mine field for newcomers trying to make meaningful contributions to this site. So let's be constructive. I would like to invite users in the know to help me assemble a compendium of generally accepted guidelines/conventions to this site. Answers would be preferred over Comments. I'd appreciate it if you would avoid bringing up anything potentially controversial here. (You could always create a different question in Meta about a particular item or set of items.) Also note, this question isn't about mechanics.
Here's another one: A word to mean the act of making two things equivalent?
Please set mentions in italic.
This is also confusing. I see many people setting their word or phrase proposals in bold.
I found another one!
'‘If we accept the axiom that trivial [/very basic] questions are bad for the site, then the proper response to [such] a ... question is: 1.Don't answer! 2… [Vote] to close. The point is not to encourage trivial [/very basic] questions. If you post an answer or vote up an existing answer, you're implicitly encouraging more questions like it.’
