> Those non-features are also a hallmark of a site that hasn't been updated in 25 years Spivak's calculus hasn't been updated either since way longer than that, and it's as fresh today as it was in 1967. What is your point exactly? Still, what you say does not ring true to me. I was thinking about stuff like bellard.org , tygert.com or math.ucr.edu/home/baez/ ... All these sites are html-only, get updated regularly, and each update is a much larger achievement than the entire life work of an average person.
