There's a new O'Reilly Radar report on The Facebook Application Platform written by Dave McClure that will be available this month (October 2007) and it costs $149.00 - as detailed in Facebook Application Platform listing on O'Reilly's Radar Site.

If you always wondered if you, too, could be a Facebook Developer, then this book is for you (at least, O'Reilly would like you to think so) and this is what you'll get out of the report:

"..

• Sizes up the Facebook opportunity–who's making money, and how?
• Lays out best practices of marketing with Facebook Applications, aka Social Media Optimization (SMO)
• Identifies the top 200 Facebook applications and plots their growth rates
• Goes beyond Facebook, and scopes out the emerging widget economy

The social network economy is sizzling, and "The Facebook Application Platform" is a must-read for anyone who wants in on the Facebook opportunity.

But I also heard the Facebook platform is evolving and changing so fast, the book is already outdated (nothing new about that - many technical books are outdated before they're published).
