A more fitting hypothesis would be, "Twitter opened up a couple new paradigms of influencing people". The paradigms are complex, opaque, and subtly inter-related; quite hard to grasp for people that aren't fully "in the loop". That's why there appearance of chaos and, at the same time, we see highly organized action emerges from this chaos.
