I would like to know, whether it is in the line of MO rules to present a result and ask for "opinions" like whether it is already known or worth pursuing and, who might be interested in the result.
Currently that can only achieved if one manages to formulate another question on top of it;
e.g. asking for surface analogue of a clothoid is perfectly fine, and also communicating an answer to it. But is it also OK to post the answer to a problem that did not appear on MO?
