Mob
A bit more information on the Insta-Mob phenomenon. “Bill” sounds like a clever and sociable person, but I need 150 people to run an event of my own, plus a couple of digital camcorders. I probably should have a collaborator experienced in such things, too. And more friends. Cheese Bikini, where the group is referred to as a “Flash Mob,” cribbing from science fiction author Larry Niven, has transcripts of the invitations, and photos of Mob 3.
