I definitely think an official ettiquette should be established. Building on Germs and oblix's responses (and collecting them into a list), my suggested rules are as follows:
1)
If آپ know the answer to the question, don't ask. This should be fairly clear already, but جوابات are for سوالات آپ NEED ANSWERING, not ones that آپ already know and want to کوئز others. In fact, believe it یا not, we already have a place where آپ can do that! It's called the "quiz" section.
2)
If you're asking an opinion, make a pick instead. I've already seen some opinion related "Answers" questions. I'm not talking about, "What's the best way to make mac and cheese" kind of opinions (those can be "Answers" questions), I'm talking, "Did آپ know that the actress who plays Sharon appears in two episodes after her character's death?" These are not "Answers" سوالات because there is no سوال being asked. All a پرستار can do is say, "Yeah, I noticed," یا "No, I didn't." This is probably better served as a pick question, when there aren't multiple جوابات یا explanations that can be employed.
3)
If آپ don't know the answer, don't answer the question. Responding just to say, "Oooh, I was wondering that, too!" یا "Oh, I don't know, but I hope آپ figure it out" are not helpful to the asker, یا anyone else for that matter. Either add your own answer to the question, یا add on to what someone has previously said.
4)
If it's been said, don't be a broken record. If a سوال has been sufficiently answered, and آپ agree with that answer, instead of answering again, VOTE FOR THAT AS THE BEST ANSWER. Makes sense, doesn't it? آپ agree, and it probably is the best answer. Don't be a glory whore and repeat what someone's already said.
5)
If آپ think someone has it wrong, correct them. Just because a سوال has been answered several times doesn't mean it's necessarily been CORRECTLY answered. Feel free to add on to other people's جوابات (like I'm adding on to germs and oblix's right now) یا to correct someone whose answered incorrectly. It's OK to politely say, "Actually, the film was released in June, not October." People won't beat آپ with a stick.
And if anyone wants to add to these rules, سے طرف کی all means do so.
