I had posted about his suicide on Friday on the Daily Fact Board, but nobody took the bait or apparently knows who he is.
Anyway I figure there's a good chance that you guys might wanna reply with a RIP. His two books of essays, "Consider the Lobster" and "A Supposedly Fun Thing That I'll Never Do Again", are most excellent and among my all time favorites and I highly recommend them.
One of the essays in the aforementioned collections is about David Lynch and his filmography that Wallace wrote from the set of Lost Highway. Good stuff for movie buffs even if you're not particularly into David Lynch.
