I've seen a few questions here on meta about what kind of questions are proper. All of them have answers, but I'm not aware of any place which gathers a synthesis of what are the "rules" of conduct particular to Buddhism SE.
The lack of an official place that we can point users to turns me silent in many Q&As that I find to be ill formulated. When I'm unable to try to stimulate an improved version of a Q or A, I avoid commenting "its off-topic because .." and derivatives since, without an "official" reference, pinpointing problems is a fertile terrain for discord.
Visiting other sites (stack overflow, programmers, christianity, etc), their help center is quite specific to their domain, and thus, a very useful guide. There are often examples of off-topic questions (and which sibling site the user should go where the question would be on-topic), examples of unsuited questions (eg. "a survey of all Christian views on a certain subject"), or instructions to improve questions with unsuited formats (eg. short questions lacking context should share research done so far within the question, etc). Not to mention examples of bad question titles (and I think this question's title falls in that category).
Buddhism SE's help center, on the other hand, is too generic. It would be great to have it resourceful so we could post a "critical comment" with a link to it and then, providing specific details on how that specific Q/A could be improved (or, clarifying why exactly it is being downvoted/closed). Without official guide to refer to, interfering can be painful for both sides, were critics are seeing as hostile, pedantic, opinionated and the criticized ones feel unwelcome, insulted, lost.
So, is B.SE. in the process of formulating richer and specific instructions to be made available through the help system?
