“Yes, I more or less had it nailed down when it comes to the growth curve," he wrote. "I didn't get it completely right --- 25 years ago I was predicting I'd be asked to do an AMA on Reddit next week, but it turned out to be this week. Well, we all make mistakes.”

While working at CERN, the European Organization for Nuclear Research, Berners-Lee in 1989 presented a plan to his colleagues that suggested creating a hypertext system to store all of the organization's information in a location accessible from any computer.
