RU Sirius has a nice appreciation of the recently deceased author over at 10 Zen Monkeys. A snippet:
Robert Anton Wilson taught us all that "the universe contains a maybe." So maybe there is an afterlife, and maybe Bob's consciousness is hovering around all of us who were touched by his words and his presence all these years. And if that's the case, I'm sure he'd like to see you do something strange and irreverent—and yet beautiful—in his honor.
Jesse Walker discussed Wilson, the subject of the documentary Maybe Logic, as "the unacknowledged elephant in our cultural living room" here.
