Removing content, cuz SO doesn't allow me to delete a question. :)
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.
