The first flash mob with purpose probably won’t be political after all. Rather, it’ll be hordes of people handing out free comics. At the least, it’ll be a noble attempt, although I have an image in my mind of a bunch of people giving comics to each other rather than to random strangers. Also, the organizer is doing a piss-poor job of keeping it secret, which will minimize impact.
Helpful hint to flash mob organizers: the minute you write anything about your mob on a public forum, the media probably knows.
