Countercultures always look really small. If everyone was actually doing it it wouldn't be much of a reaction to the prevailing culture of everyone being connected and having snippy political discussions in neighborhood discussion groups.

All of this organization doesn't actually happen on social media in my social group. We pretty much all just text each other, and everyone I know and care to spend time with does this. The people who are utterly reliant on Facebook to organize their lives have filtered themselves out of my friend group.
