At the 2008 PenguiCon scifi convention, he was one of the guests of honor. On Saturday morning, I happened to be sitting right next to him at a publisher’s breakfast thrown by Subterranean Press. I didn’t talk much, though I did manage to tell him that I was a huge fan of his (and that his True Names and Other Dangers was a formative work for me, even before Gibson’s Neuromancer). I also spilled my coffee like a klutz, and narrowly avoided dousing him with it.
I got to meet him though!
