Infinite Jest is pushed in everyones face as an example of what a novel "should" be / best book ever written (yea right) and he has an evercrooning group of adorers who make Pynchon fans look reasonable and sane.

Personally I find it him to be turgid and overwrought but I get why people enjoy him and come back. His essays are entertaining but I've never gleaned any great insight or inspiration from him.
