What makes Scott Alexander's writing so great?

I lost interest in codex after reading https://slatestarcodex.com/2017/08/29/my-irb-nightmare/ because it was just too Straussian for me to follow. But he is a prodigious writer and I admire the energy to write so much.

Scott seems like a highly intelligent person, and much of his writing is fascinating.

However, from my point of view, often he can drone on endlessly about some tiny, arcane intellectual or philosophical issue, and when that happens I just tune out.
