The thing about the Internet is the openness. People can link to each other themselves.

When a business becomes successful seemingly overnight, no one knows about all the months and years you've invested, all the projects you've tried before that didn't work.

It's extremely hard to build a company with a product that everyone loves, is free and has no business model, and then to innovate a business model. I did that with Kazaa, had half a billion downloads but that wasn't a sustainable business.

Skype is for any individual who has a broadband Internet connection.

If you could utilize the resources of the end users' computers, you could do things much more efficiently.

And the VCR did the same thing: the movie industry thought nobody would ever watch movies any more.
