Paul Graham writing about good taste (and people actually reading this) looks to me like either good trolling on his side, or just the usual startup misery - an extrovert narcissist convinced that he has intellectual capacity to analyse absolutely everything (and that analysis is worth sharing) because he's running a VC. It's sad either way.
I think it's the latter - you see the same thing with Naval too, as well as a slew of rationalists who seem to consider it their role in life to reinvent sociology from the perspective of a software developer without having read any of the existing academic works.
