Is there any proscription that I'm not aware of that says you shouldn't ask questions you know have a good chance of being a community wiki, or that you already know the answer to?

I'm trying to come up with questions that I think would be great general knowledge references, but wasn't sure if that was a "frowned upon" practice.

  • I also would like to know if this is a good thing or not. I've also been asking questions that I thought would be "canonical". Commented Apr 3, 2015 at 18:13
  • You can answer your own questions as long the question is clear enough and it's treated as any other question.

  • Personally I think you should ask questions that you are interested in. If you later find out the answer, then it is ok to post an answer to your question.

    @PatrickHoefler, why don't you turn your comment into an answer?

  • @Mew Why not sharing knowledge? Commented Apr 5, 2015 at 2:36
  • @FranckDernoncourt, if people wanted that knowledge, they would ask for it themselves.

    @Mew One doesn't always think if all possible questions. Also, posting a Q&A can allow the poster to write down knowledge fresh in his mind before he forgets the details. Commented Apr 5, 2015 at 5:02
  • @FranckDernoncourt, good points, i'm convinced.

Let me start with your second question:

Is it OK to ask questions you already know the answer to?

… it is not merely OK to ask and answer your own question, it is explicitly encouraged.

With community wikis, things are less clear-cut.

Most of the time, you should be asking yourself “How can I improve this post so that community wiki isn’t needed?” […] Community wiki is for that rare gem of a post that needs true community collaboration. That’s when community wiki shines.

And as a general rule of thumb (from the same source as above):

A site should never have more than one community wiki question for every hundred questions.
