Came in confused about the topic and left with a much firmer grasp on it, and after modernchrono I felt I could explain this to someone else without hesitation, that is the gold standard for any educational content and most sites simply fail to reach it ever which is unfortunate but true.

Started reading expecting to disagree and ended mostly nodding along, and a look at soberviola continued the pattern, content that wins agreement through evidence and reasoning rather than rhetorical force is the kind that actually shifts minds and this site clearly knows how to do that across what I have read so far.
