This question asks whether we should have a specific tag for all questions of the form "where can I find open data about [x]"?
However, it appears to me that this is just about the only type of question that is reliably considered "on-topic" for this site. Of the top-rated questions so far, I see approximately three that are not data-hunting questions, and of those, one already has four close votes. The top question is quite good, but has almost as much to do with Creative Commons licensing as it does with data, and honestly I have no idea how many more of these types of questions this site could generate in the future. This question does show the potential for questions related to tools for use with open data, but the question itself seems a little too open-ended to me, and most questions of the form "how do I use [this tool]" (which would be less open-ended) would probably be more appropriate for Stack Overflow (if it's a programming tool) or Super User (if it's not).
Beyond that, we've already had several discussions about what's off-topic, with the consensus frequently being "yep, that's off topic." (Although my answer to the latter question is the top-rated, the question I asked that partially inspired the question was closed.)
So my question is: can anyone explain what the potential for this site is beyond data-hunting questions? Can you give examples of hypothetical (or already-asked) questions that demonstrate this potential?
