The Socratic badge's criteria says
Ask a well-received question on 100 separate days, and maintain a positive question record. This badge can be awarded multiple times.
Unlike most of the other badges' criteria, this seems pretty subjective and not very clear as to what a "well received question" is. For instance, I have asked 65 questions, but according to the badge tracker only 54 of them are "well received". So what exactly qualifies as a "well received" question?
