Tim Berners-Lee describing FOAF to Tom Gruber as Daniel Schwabe listens in at ISWC 2006. I had a momentary opportunity to listen in for a few minutes. Pat Hayes made the photo. Funny story: Tim said I could only stand there if I had a foaf ID -- I seriously do not think he thought I would; so he was most surprised when I said, "Why yes, I do!" and so he had to let me stand there for a few minutes to listen in on the conversation.
