I think asking questions that you actually want answered by the community and that can help you gain some knowledge is the best way of asking questions. There is no limit to how many questions you can post BUT in order to garner quality posts musing needs quality questions. They should be clear , specific and in most cases be able to produce an open ended answer unless of course pure logic is needed and there is a definite answer.

Asking a bunch of random questions just floods musing with spam. There are no stupid questions but there are spammy ones.
