LW has a problem. Openly or covertly, many posts here promote the idea that a rational person ought to be able to self-improve on their own. Some of it comes from Eliezer's refusal to attend college (and Luke dropping out of his bachelors, etc). Some of it comes from our concept of rationality, that all agents can be approximated as perfect utility maximizers with a bunch of nonessential bugs. Some of it is due to our psychological makeup and introversion. Some of it comes from trying to tackle hard problems that aren't well understood anywhere else. And some of it is just the plain old meme of heroism and forging your own way.
Also the first few dozen chapters of HPMoR are terribly written. It is rather horrid, strained, constipated writing. Particularly if you view the early releases of the text, not the revised text that is currently available. The writing got decently good towards the middle, and was top notch by the end. But that was after thousands of pages written and lots of feedback on every chapter. No surprise, lots of writing practice and (critically, to the point of this thread:) feedback leads to becoming a better writer.
I feel uncomfortable criticizing HPMoR for its writing when it clearly succeeded at its job beyond all expectation.
