(I don't know if this is on-topic on MathOverflow-meta. In case it is not, please, let me know.)
I see that many active users of MathOverflow are not as active on Math Stack Exchange; for this reason, I would like to draw their attention on this question that I recently asked on Mathematics Stack Exchange, in the hope that some of them will spare some time to share their insights on the topic.
Kindest regards.
