I just finished both listening to the audiobook and reading the paperbook of Seth Godin's newest book Tribes.  Of all the books I've read/listened to this year (and the list is considerable, > 25), this one shot straight to the top of my list.

 

I highly recommed this book to everyone (I'm buying many copies to give away as Christmas presents).  And for those of you with Audible accounts (or the willingness to create one), you can get a FREE copy of this book HERE.  Also, if you use iTunes (blah), then I believe if you search you will find it for $0.99. [Correction: Looks like that was just for a limited time, it's now $5.95]  Seth is a great narrator, so I almost would recommend the audiobook over the print copy... but if you're like me, after listening to it, you'll want your own print copy too.
