Not to denigrate Joshua's achievements, but I'm not really into web stuff like most of you guys. The big topics around here are python, ruby, erlang, myssql, rails, et al. If I were to learn a new language today, I'd pick something like Z80 assembler. That makes me less marketable, but that's what appeals to me.
Andy Hertzfeld did his best work in the severely constrained environment of the early Macintosh. I'm equally impressed by guys who were able to write games for the Atari 2600 and the Intellivision in 2K of ROM and a couple hundred bytes of RAM. That's the kind of stories I like to hear, for better or worse. Not surprisingly, I've read every story on folklore.org several times.
