I'm not sure what your point is. What's the fallacy? I haven't seen any examples of this sort of discussion question that are good arguments for allowing them on SO.

Like. maybe, avoiding database development mistakes made by application developers?

Nobody's saying don't post that information. Just, don't post it on Stack Overflow. There's plenty of other places to post long-form pieces about general discussion questions. The best of which is probably a blog. If I want to avoid database development mistakes I can google for that question pretty easily. I don't need to go trawling through Stack Overflow to find that sort of generic advice, and I don't need to drown out other people's legitimate questions with my own fluff question asking for a rehash of widely-known database development practices which I could have found elsewhere.
