Two links which I recommend:
- Kottke's first stab at a post, mostly because you should be reading Kottke anyway, but also because his judiciously chosen excerpts and links is a great (and manageable) way to learn more about Wallace.
- The seriously beautiful thing going on now at McSweeney's. They set up a forum for rememberences by almost anyone. It's fantastic to see non-professional writers, people who had maybe brief encounters with DFW, remember the man. Not surprisingly, many of these letters are written by his former students; it sounds, from all accounts, that he was a better teacher than he was a writer. A must read for anyone who teaches.
