This has always been the case. I think I first stumbled across less wrong in the early two thousands when I was a maths undergrad.

At this point it was mostly Eliezer writing extremely long blog posts about Bayesian thinking, and my take home was just, wow these guys are really bad at maths.

A good mathematician will carefully select the right level of abstraction to make what they’re saying as simple as possible. Less wrong has always done the complete opposite, everything is full of junk details and needless complexity, in order to make it feel harder than it really is

Basically, Eliezer needs an editor, and everyone who copies his style needs one too.
