HyperScope: The Story: "You may know that Doug Engelbart built the first collaborative hypertext system in the 1960s, among his many other firsts. What you may not know is that that system -- NLS/Augment -- still runs, and that Doug and others continue to use it every day.

Augment has capabilities not found in any other software, features that make us smarter and more productive. You can read about many of these capabilities, but you can't actually experience them first-hand (although this is changing). This is a huge loss, and not just for those curious about history. With today's high-speed networks and computers, some of these capabilities are potentially more relevant today than they were forty years ago."
