In 2003 the network stopped being pages and started being people.
2003 brought LinkedIn and Skype: the web reorganising itself around human connections and free voice across the world. Spaceflight also absorbed the loss of Columbia and its seven-person crew during reentry in February.
In 2003 the shape of the internet changed under our feet. LinkedIn launched and turned professional life into a graph. Skype launched and made a call from Dubai to Delhi to California free, over the same wires that used to just carry pages.
The web had been a library. Now it was becoming a room full of people.
I had spent years thinking about addresses and infrastructure, the plumbing. 2003 was when it became obvious the plumbing existed to carry relationships, not documents. Every company I have started since is really in the business of connecting people, whatever the product on top happens to say.
