Thanks to Mark who pointed out that Ted Nelson, the inventor of hypertext is turning 70. Specifically, Mark linked to the birthday lecture Ted gave in anticipation of that birthday. It’s a massive download, but if you want to watch a man with a keen intellect, and omnivorous interests discussing a range of topics, it repays the investment of time and bandwidth. Somehow, I managed to get through an entire Masters degree in multimedia without becoming familiar with Ted’s work – certainly my loss.
