Love this book. I did a short interview with the author Brian Dear about his writing tools + process a while back. Perhaps my favorite anecdote is that he started working on this book in 1985, using MSDOS and later a NeXT cube for his notes. The authorial process truly experienced the full gamut of personal storage mediums over the years.

It's fantastic - I read very little book length non-fiction (because I largely read books in bed to relax, 10k+ word essays or entire documentation sites are a different matter), but it was gripping, thoughtful, beautiful, and so, so much worth it.

It made enough of an impression on a subset of the users that I believe the free-to-access cyber1 system is still going and has (just) enough people on it to retain some of the social aspects.

I also liked TFOG. I wish PLATO were more widely available (especially with all of the software for education, science, communication, and [importantly!] games) for examination, emulation, experimentation, and general use.
