Nice piece in Wired this month (HT Gareth K) that looks at self-organising crowd behaviour.
Not sure it adds anything to the stuff we've previously pointed at e.g. here, here, here, here, here, here and of course here
And of course it provides a good challenge to Behavioural Economics, forcing us to think about behaviour change above the level of the individual (which is where BE stops)
That said, this stuff is always - as G would say - awesome (literally)
