But PG wasn't an established authority back when PG was writing fast. I remember reading PG in 2006, and you'd read lots of snarks on the tech forums of the time (Slashdot, Digg): who is this guy, and why should we listen to this bored washed up multi-millionaire who sold his startup to Yahoo? He hasn't done anything of note in the past 10 years! (They said the same thing about Philip Greenspun too, who was also writing at a faster clip back then).

Look, at the end of the day, "established authority" is only loosely correlated with worthwhile meaning. At some point you're going to have to move past the author and evaluate the words on the page on their own merit.
