With respect, I would like to see some evidence of your assertion that anonymous communication results in higher quality content than when the question answerer is known. The highest quality information content I'm aware of is in textbooks and scientific journals where the author's reputation is on the line. Contrast that with the wall of a public restroom, which is pure shitposts.

You might be correct if the assertion is the latter is more reflective of how an average Internet user actually feels at any given moment but won't admit in polite company.
