Sitting in the Flickr archives is a nearly 10-year-old document uploaded a couple of years ago by its author, Jack Dorsey (@jack), who started Twitter in 2006 along with co-founders Evan Williams (@ev) and Biz Stone (@biz). This incredible handwritten document by Jack Dorsey is the original blueprint for the social networking service Twitter.
The Roots Of Twitter
Twitter didn’t just fly out of thin air and land on a branch. As Dorsey explains, it has conceptual roots in the world of vehicle dispatch — where cars and bikes zooming around town must constantly squawk to each other about where they are and what they’re up to.
It was when Dorsey saw these systems through the eyes of the social, mobile Web, where anyone can squawk from anywhere, that Twitter’s “Big Idea” was born.
