The key distinction to make here, in my mind, is that all questions are ultimately in service of the people answering them. That is the audience you need to satisfy if you want to have any hope of creating and sustaining a community of peers learning from each other. The minimum bar for a question is not “is this on-topic?”, but rather “is this somewhat interesting and on-topic?”. I’m not saying every question needs to be utterly fascinating, but please endeavor to make your questions more than a constant stream of no-duh underhanded softballs requiring nothing more than a quick cut and paste from Wikipedia, IMDB, or some other standard internet reference site.
There’s nothing useful any expert can learn from ultra-basic questions. Allow your Q&A community to fill itself with enough “General Reference” type questions and you’ll soon find no experts at all.
StackExchange sites have a very good brand. If I google a question like "How do I jump in Mario?" and see gaming.SE, I definitely click it, and 99% of the time find the answer faster than I would have on some more long-winded forum.
I think of it like, with questions that are too easy the problem is basically the askers are not doing their part to create a good repository. Likely they will be both answered and downvoted. This makes enough sense to me.
In either case, sometimes the simple questions are quite polished
or detailed and sometimes the answers are very good explanations,
and beat the other answers that appear in search results.
