The parallel thing I see happing is the strengthening of subcultures. Although the internet is bringing the world closer together, it also seems to be allowing like minded people to build lasting subcultures. Reddit has several of these. This is a pattern I have seen a lot. These subcultures might have sprung up before but after the initial enthusiasm dies out, the subculture moves on. Now, it seems that these subcultures persist and keep growing, building group identity, language, and camaraderie. The Ron Paul supporters have stuck around for years because of this and now they have the growing organization to push through to the mainstream, but it is the lingering subculture behind it , this strong foundation, that is allowing them to push through the normal barriers that would have prevented this in the past.
