My title may not be the best of titles. But it appears to me that matheducators.se receives its share of opinion-based questions, e.g., When should students stop receiving tutoring?. There are a few more I've come across recently, but the question I link is an example of what I consider an opinion-based question:
"Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions rather than facts, references, or specific expertise.
Perhaps questions which are "primarily opinion-based" have not been of great concern on this site; if not, please educate me. I am rather new to reviewing questions and answers on this site, so it is very possible such questions don't come up often enough on this site.
Admittedly, the question could reasonably be closed as "unclear what you are asking", given that the answers, and many comments, point out that the asker hasn't given a clear definition as to "what counts as tutoring?" Depending on each matheducator.se user, what each considers to be "tutoring" may not fit, as already indicated in the comments to posts, the asker's definition of tutoring. In any case, I look forward to feedback.
