All technological breakthroughs start with a small "elite". Think about cellphones, for example. Now just about everyone has one. The same will happen to innovations such as Twitter.

Between Twitter and Facebook I have nearly 70,000 followers, so my colleagues receive the responses. They show some of them to me, and I am always interested to read what people have to say. I filter all the information that reaches me, from letters in the newspaper, to conversations. There are many influences that shape my decisions, and often people on Twitter are thinking along the same lines as I do on an issue.
