I've been reading some posts about canonical questions, and am still not sure what they are. Examples:
Should we make a canonical “How to send data using serial?” question?
Is a canonical question like what we would call in Australia a Dorothy Dixer where you ask a question to which you know the answer? For example:
Q. (by Nick) How do interrupts work on the Arduino?
A. (by Nick) Glad you asked! I'll explain them ...
Or is it (as some of the links above seem to indicate) just improving existing questions?
I could probably do some "reference" questions if they were wanted, I just want to clarify if that is what is intended by the expression.
I also notice a checkbox: "Answer your own question". What does that do? Does that mean you put the question and the answer into the same post, or does it indicate you are planning to answer your own question?
