Twitter is not a technology. It's a conversation and it's happening with or without you.

It's the same reason why someone has a Web page or why people feel comfortable going on reality TV.

Some of the power has shifted from companies to people. Using social media tools (blogs, wikis, tagging, etc.) more individuals are creating semi-spontaneous 'groundswells' of opinions to which companies and other institutions are realizing they must respond. From marketing to consumers organizations are being pulled into engaging with individuals.

If you think you are in control, you're fooling yourself. As soon as you start listening, you realize you're not in control. And letting go will yield more and better results.

Then they show up at the door and the reality is that they are 5-foot-8, 240 pounds and have not run a mile in years. A background check is not going to help you with that.

People often say to me, "How come you don't want to be CEO of a company?" And I tell them, "I don't want to." I know I can do it, but I don't enjoy it. Why does that have to be the definition of success?
