Clearly, we get a lot of very low quality questions and answers here on this SE (particularly ones of the "what is this song [link]?" "Maybe it's [X]?" format). However, we also have another problem --we have a low user base and few new questions.
After a discussion with @Dom, I want to open this question to the community. What should we do with low quality questions and answers? I'll give my own answer below, but I'm interested in soliciting competing points of view.
Follow-up questions based on Dom's comment below: What should an answer look like for questions that attract a lot of low quality content? Is any answer acceptable if not enough information is given? How do we handle questions with answers that are only answerable by the OP who never comes back?
