I'm well aware of
nonetheless I was wondering whether is it appropriate to clearly specify what I'm doing, rather then posting it as a normal question.
The specific case I'm referring to is my recent 'self Q/A' here
I introduced the question with this note
This is not a real question, but just a way of bringing to StackOverflow this nice trick that I recently discovered reading this blog entry by Erica Sadun.
but it feels not completely ok with the StackOverflow question format.
Should I leave the note there or remove it?
