I was wondering if:
- it's OK to post these (properly tagged as 'puzzle's of course), knowing that it's not a 'real question' in the sense that the one who asks (usually) knows the answer?
- others would be interested?
- the 'puzzle' tag (or some other...) could be used just to identify these questions I guess, so that it would be clear to everyone;
- is there really always a need to pick a 'best answer'? Note that lots of questions being asked are quite subjective in nature, and do not have any 'best answer'...
