Dave Winer, on what goes around, comes around:
There's a cycle to tech. Something new and wonderful comes along with unlimited potential. The early users of it trip out. Some of them learn how to program, some of them already know how to. They become the developers of the new thing, and it becomes a platform. Then the investors notice something happening, and the business guys, and press people and money starts pouring in and companies start. More users. Lots more users. And more money and more press and more business people. Soon its a boom.
