(I ain't much younger, so I know I have no room to talk.)
Since I live in San Diego and all, I'll be there Sunday! I'm going more as a new KDE4 user (which I've documented on Planet). I plan to hear the Plasma talks, maybe take in the keynote or a few other things. I'll at least drop by before/after your talk to say "HI from the token non-programmer."
Who knows, I may even see what's going on Monday or Tuesday . . . Tuesday's schedule is rather vague on what's actually happening.
