Free Article, Journal, Video and Book, tell you where to get some cool free resources!

He mentions that the hot new book "FREE" by the editor-in-chief of Wired Magazine, is free in some forms:

After studying what other authors had done with free digital books, my publisher and I decided to make FREE free in as many formats as possible to encourage sampling without competing too much with the premium hardcover. It's free on Google Books, Scribd, the Amazon Kindle (and Kindle iPhone app) and Shortcovers (these are time limited, from one week to one month). The full unabridged audiobook is free at iTunes, Audible.com and as downloadable MP3s at Wired.com (no time limits).
