Libertarians and conservatives aren't using the Internet to organize in the same manner that the Bolshies did last year. All sides are leveraging the Internet, yes. But fittingly, the left's method relied on centralization. It was a top-down affair: meetups and rallies were planned and organized from the top-down. The party machine was involved at every stage.
On the right, this is simply not the case. Santelli ignited a spark that was distributed and magnified via the Internet. The original day of tea parties was highly-decentralized and 9/12 was remarkably decentralized and ad hoc. There still isn't an accurate count of just how many towns saw protests that day or on 9/12. Individuals just bloody showed up. Individuals chartered their own buses. It was pretty damned interesting to see how huge it was, despite the lack of central planning.
