Ward is best known as the inventor of wiki technology. Now, as the Nike Open Data Fellow, he has set out to change the world by doing for numbers what he's done for words: use technology to give them depth and meaning that ordinary people can depend on every day.

Ted Nelson envisioned a new way to write and dubbed it hypertext. His various incarnations of Project Xanadu explored variations of his two-way link but all failed to become popular.
