Removing content, cuz SO doesn't allow me to delete a question. :)
What is meta?
- Any Stack Exchange user can ask a question
- The community provides support, votes on ideas, and reports bugs
- Your voice helps shape the way Stack Exchange operates
Let's start with the specifics of your case:
Speaking with regards to the general case, I don't think that SO is "overzealous" in closing questions. SO gets a lot of questions per day, and it has to establish strict boundaries on what it can and cannot accept to maintain a high standard of quality. There are a lot of other Stack Exchange sites, however, and some of your questions may fall within the scope of existing sites.
