Kudos to Matt Dickman who released a free ebook with essential data about Facebook.
The first part of the 24 pages ebook covers the stats (reach and socio-demo) of Facebook and the second part explains the marketing possibilities. What I really like about Matt's work is that he's only presenting facts.
Here is the link where you'll find 2 versions (high and low def) of Matt's ebook. Enjoy!
