Deep, intelligent, well-read individuals rarely have to go to any great lengths to point out how deep, intelligent, and well-read they are. It's almost as if they don't have anything to prove.
Which makes the booksnobcrew kind of like those guys that drive around in those jacked-up cars. You know the ones I mean. The big SUVs or phallic-like sports cars with the bass cranked up and the shiny!yay! rims and such -- and they're driving them because they're soooooooo into cars and you're supposed to be all impressed, but really you're just sitting there thinking, "Sorry about your tiny, tiny penis."
