Since his suicide in September, there has been a lot of goodstuff on the web about David Foster Wallace. This piece from The New Statesman may not be the best, but it's definitely worth reading, and it shows the most evidence that the writer has actually made his way through Infinite Jest—which might not be a prerequisite for appreciating DFW (I think short stories like "Good People" and "The Depressed Person" and "My Appearance" and (especially) "Good Old Neon," along with a smattering of the essays, would do the trick) but is important for reflecting on this writer's life and development.
This [blog] is my Savings Bank. I grow richer because I have somewhere to deposit my earnings; and fractions are worth more to me because corresponding fractions are waiting here that shall be made integers by their addition. —Emerson, Journal (1834)
