I am wondering what is the etiquette regarding Te[X/ch]nical questions asked on the main chat room.
I have indeed seen people (including myself) posting their questions on the chat and being answered. However, it is not really convenient (notably for posting MWEs), it might interfere with others' discussion, and (more importantly) knowledge is not stockpiled as other would hardly retrieve the question later.
My current personal guideline is thus the following: I ask on chat when I think my question is silly/simple and not very valuable for others. In other words, if I think that the question could be answered in less than one line and one minute by someone who has the relevant experience.
However not quite sure if it really works that way. I thus would like to know when I should ask on chat (if ever), and when it is better to write a question.
