Reading that 15-odd years ago got me started with web development.
I love that the whole book was online but also in a very slick coffee table format. With a bracing sense of humor and not afraid to try and distill very technical topics for less technical people. There is something of the DIY, can-do, participatory side of 90s computer culture in there. Deeply.
I've really enjoyed reading Greenspun's stuff and this is a great way to describe his writing style.
just like the 'interconnections' book from radia-perlman, i really dug the irrreverent attitude though...
