[ this is perhaps pretty close to Question/answer ratio etiquette in Stack Overflow? and maybe a few others...but it seems at least a smidge different than "exact duplicate" to me... ]
It seems that "a lot" of "stupid" or "bad" questions (asked only for rep?) come from people with few answers. While I'm by no means any type of an expert on SO (with a measly 1000+ rep), I answer a whole lot more questions than I ask--by a ratio of about 10-answered to 1-asked.
Is there anything on SO that is driven by this ratio? Should there be? If so, what would be a "good" question/answer ratio?
While we all want people to feel free to ask questions, there is a lot of benefit in both answering questions and taking the time to write a decent question.
