I think you have something here.
Maybe we gravitate to the opportunity to ask questions that would be too pointed or socially 'charged' to address directly to our immediate co-workers, colleagues etc.
That is right on for me. I had been thinking in terms of repetition compulsion stemming from growing up in a small conservative Christian home town but having to be careful of people's feelings. Here I can renew debate with the forces of judgemental parochialism.
The other value for me is that I am challenged to clarify my thinking, understanding, and expression. And I discover where I need to focus attention, renew study, or explore further.
