Seth Godin is one smart dude. I got this offer today - buy his new book, and you get to listen to a 1 hour conference call.
Shouldn't this be what musicians do? Authors are facing the same type of piracy pressure that bands are facing. This is Seth's responsive, provide a little more value add, something personal, and charge for it. I hadn't planned on buying the book but hearing him talk pushed me over the edge.
I'd shell out for a 30 minute call with Jeff Tweedy, Jim James or Eddie Vedder. Personalization makes all the difference.
