We have spent some time discussing questions that are not perfect. When a new user shows up, and doesn't know how to ask a question or what questions to ask, seeing lots of people talking about what doesn't belong can send the message, "Don't ask questions; you don't belong here."
- identify some questions that have been asked so far during the beta that really seem in some way to be perfect for this site, and
- discuss what it is that makes them good questions.
A set of great questions, with explanations for what makes them great, would be a very useful addendum to What topics can I ask about here? in the Help Center.
