Something that just occurred to me and probably needs to be discussed - the balance needed between professional and enthusiast questions. There hasn't really been any problems here thus far, but this needs to be discussed.
Ultimately, any clear question, whether it takes an answerer 10 seconds to find on Wikipedia or such probably should be answered properly. I have seen on some other sites, where more learned members ridicule the questioner - the net result is often that , for better or worse, the questioner becomes discouraged and does not bother anymore. Whereas by modelling good answers and questions would more than likely help them.
If the question is badly written (unclear etc), downvote and flag/vote to close - public ridicule does not look good for the site at all. I'd be interested in what others have to say about this.
