An article at IndyMedia notes the protest set's growing interest in the flashmob phenomenon. The most obvious problem is that a genuinely flashmob-style protest would be less well suited to drawing big-media attention. Of course, maybe that's no longer the goal… which would be a welcome sign that activists are noticing that all but the biggest protests slip under the radar anyway, and those that do get covered often alienate as many people as they interest. (I recall reading some sociologist argue a while back that the Vietnam war would have ended years earlier if people weren't so hostile to the anti-war protesters.) It'll be interesting to see where this goes.
