The next wave of the social graph is empowering services like Airbnb and Lyft that give people the chance to have that physical interaction. People are more open to that because of Airbnb. Airbnb took couch surfing and took an additional step.

The solution to transportation inefficiencies lies at the intersection of collaborative consumption and the social graph: Shifting transportation from ownership to access.

My vision for the future of social transportation is one that places more value on information and community over a physical product. Move over, multi-billion-dollar high-speed rail infrastructure and welcome, social information-based solutions.

I'm surfing the giant life wave.

I always preferred to hang out with the outcasts, 'cause they were cooler; they had better taste in music, for one thing, I guess because they had more time to develop one with the lack of social interaction they had!

I think we've built a bit of a culture and a market around people who are open and seek out that social interaction.
