The way you can understand all of the Social Media is as the creation of a new kind of public space.

Most teens aren’t addicted to social media; if anything, they’re addicted to each other.

Business culture operates differently in different cities around the world. But I don't think it's possible to design one system that incorporates all social norms for networking. Human beings are just too diverse.

LinkedIn is very good for browsing relationships and hooking into your contacts' networks. It re-connected me with high-level execs I hadn't talked to for some time, who then helped me close various deals.

Give me one other part of history where everybody shows up to the same social space. Fragmentation is a more natural state of being.

Social networks are like grease - in some cases, gasoline - for our personal business networking machines. If you aren't plugged in, you will be out-done by better-connected, hyper-networked colleagues and competitors.
