Is a perhaps somewhat cervellotic but not HARD question, regarding mathematical logic, suitable for MO?
4$\begingroup$ No, it's not suitable. $\endgroup$– Emil JeřábekSep 3, 2014 at 10:18
5$\begingroup$ For anyone wondering: 'cervellotic' did not appear directly in the online English dictionaries I looked at, but it seems to be extracted from Italian and means 'weird' or 'odd' or 'strange'. $\endgroup$– Todd Trimble ModSep 3, 2014 at 11:35
$\begingroup$ @ToddTrimble: So it doesn’t derive from cervesia as I assumed? That’s a shame. $\endgroup$– Emil JeřábekSep 3, 2014 at 12:31

In general, questions / "puzzles" where you already know the answer are not suitable for MO. Also, it is usually not welcomed to immediately cross-post questions from other sites here -- thus even if a question asked on MSE would be suitable for MO as well, one should wait at least, say, a week or two whether the question gets satisfactory answers already on MSE. Regarding your particular question, I don't think it would be suitable for MO.
