Here's all the evidence you need that Infinite Jest by David Foster Wallace is a great book.
-I carred it around urban metro Boston for a few days, and got no less than three comments from complete strangers about how much they liked it, including from the conductor on the Commuter Rail.
-I was walking in front of North Station and a woman passing by on a bike, who was presumably homeless, said "Great book. Great man. Too bad he offed himself." You can't say it much better than that, and that's really all you need to know about the book.
-I am still almost completely unable to describe the book to people who ask me about it.
I strongly urge everyone to read it.
