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.

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

Along with planes, running water, electricity, and motorized transportation, the internet is now a fundamental fact of modern life.

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

The things that make us safest from others make us least from ourselves.

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.

Neither privacy nor publicity is dead, but technology will continue to make a mess of both.
