"On the flipside, to the extent that v2 social networking allows people to be themselves in all the different ways they wish to be, the more likely it is they become close to people who see other parts of the world in ways that differ from their own. Critically, though, unlike Facebook or Twitter, that exposure happens in an environment of trust that encourages understanding, not posturing. This has been the case for me: I am in private groups with plenty of folks that I disagree with about a whole host of things, but because we share a common interest, and are ok being trusted friends on that vector, I have learned a lot about why they believe what they believe about a bunch of issues. I think it helps my analysis, and I think it makes me a better citizen. That certainly isn’t our expectation of social media today, but that is because we are stuck on v1."
