Loved Inifinite Jest when it came out, and really enjoyed some of his short stories. Some of his essays were quite insightful, although I certainly couldn't read more than a couple of them at a clip. Hated seeing his writing devices grow gimmicky as other subsequent writers lifted them en masse (Morford, Eggers, etc). No idea what was going on in that head of his, but from a purely selfish perspective I'm sad he wasn't able to write another novel and perhaps reinvent himself before cashing in his chips. RIP.
