I'm thinking this could really take off - but maybe we could go further . . . instead of programming e-commerce, we could print out all of the information about our products, add a contact number and just mail it to people. The possibilities are endless. Perhaps instead of a truly semantic web, web 3.0 will all be about paper, postage, and red crayons. Whatcha think?!
(Side note: the books are good enough that I'm willing to buy a red crayon if it'll get me some!)
