I often accidentally call them "Grateful Dead Conferences" because so many tech people I knew and worked with in Silicon Valley and regularly saw at computer conferences and trade shows would show up (like you, Fen, Gilmore, Barlow, etc).

(That was back when the hippies were in charge, before the frat bros took over.)

Q: What did the Deadhead say when he ran out of marijuana?

A: "This music sucks!"
