I see no problem in this, providing it is done for the "benefit of the community": namely, if an expert sees a lot of people making some trivial error then they could ask-and-answer a question on it, thus ensuring that those making the error learn of their mistake. Or if someone sees a question that they have a great answer to, but (say, in the comments) it becomes clear that the original questioner wouldn't understand the answer, or that it wasn't really the answer they were wanting.
My brief reading around stackoverflow is that this is perceived as Good Behaviour, again providing it is done for the benefit of the community and not for the benefit of the person doing it. But the reputation system should be sufficient to distinguish these cases.
]]>Rules does not apply to everyone
I disagree. I think that the same rules should apply to everyone. The bonuses you get for reputation are perks, but rules still apply, one way or another.
By the way, to accept your own answer you must wait 48 hours.
]]>Answering your own question is certainly not problematic as a general maneuver; the general presumption is that this is something you would do if you posted a question, and later came up with an answer. On the other hand, I'm not sure that there is an official policy about posting a question with the intention of answering it yourself. I think we may just have not discussed the issue yet (I don't think I've seen anyone suggest it was happening before this thread). So, right, I guess we should all discuss this now.
I'm of two minds on this point. One says that this is clearly not how the system was intended to work, and in particular, having someone do this would be somewhat distracting, and take up space on the front page. On the other hand, MO is also here for posterity; if you write a question and immediately answer it, you're creating new content on the internet that has a reasonable chance of being useful to people in the future. If you want to do that, and people want to vote you up, who are we to say you shouldn't. As long as the questions are on-topic, the rest of us thinking you're a bit weird seems like about the right level of chastisement.
