It'd probably be less intensive for the server if it used HTTP KeepAlive and no delays, it's not very much data, so minimizing HTTP overhead by "getting it over with" is probably more polite.
woops! Thanks for pointing it out!
The “examples” appear to be the complete output, i.e., are actually full copies of all the essays. That's probably not a great idea given that there's no explicit license on the source material, that he's said elsewhere he'd prefer people link rather than rehost, and has a book of many of the essays who's publisher may or may not have purchased the distribution rights.
