In bicycle culture they do an unorganized event called critical mass; in the past I've seen these events hijacked by a "xerocracy" where someone shows up to the meeting point, starts handing out (xeroxed/photo copied) fliers with a map with a different route and then take off in that direction and.... most of the crowd follows them. Different kind of Do-ing but very effective in truly flat hierachies when executed well.

This is more common than you think when you get into alleycat races where you're racing for money.
