Scott Alexander somewhat addressed this in “Why Do I Suck?”:
If you have a small blog, and you have a cool thought or insight, you can post your cool thought or insight. People will say “interesting, I never thought of that before” and have vaguely positive feelings about you. If you have a big blog, people will get angry. They’ll feel it’s insulting for you to have opinions about a field when there are hundreds of experts who have written thousands of books about the field which you haven’t read. Unless you cite a dozen sources, it will be “armchair speculation” and you’ll be “speaking over real academics”. If anyone has ever had the same thought before, you’re plagiarizing them, or “reinventing the wheel”, or acting like a “guru”, or claiming that all knowledge springs Athena-like from your head with no prior influences.
