Keep music from the web in the web. Don't go to a music blog, download a track, and then listen in iTunes.Instead, he advocates bookmarking and playing music in the page that contains it, once again returning to fundamental link between URI and resource, between index and content.
What, for that matter, is a Content Management System? The term is a necessary evil; it's not like it is meaningless. But when you use this term to refer to WordPress or Blogger, I get an uneasy feeling, and reading Gonze's comment really cemented for me the reason why. The text on the page in front of you?
