"Wikification of Sun"
A few design folks at Sun have created a wonderful YouTube video called Wikification at Sun. In six minutes, you are shown the history and rapid evolution of the publishing world at Sun, from
troff to FrameMaker to AdeptEdit to blogs to wikis, thanks to the inventions of GUIs, formatting and structuring tools, and Web-based interfaces.
As someone who has used most of those tools over the years and lived through the changes, I find the video truly fascinating. Well done!
