Sometimes a book needs to be set free. When I received my second copy of Seth Godin‘s Tribes: We Need You to Lead Us, it was with the proviso that it be passed along. Anyone who pre-ordered the book and joined Triiibes (as I did, though I don’t hang there much) was sent a second copy of the book as a gift and told to pass it along to someone who needed to start a tribe.
I did this, and it’s a good example on Seth’s part of giving something for free in the interest (at least partially) of increasing sales. More exposure to your message, even for free, in the short term will mean more ongoing sales in the long term. It’s Seth Godin putting his money where his mouth is (before the fact), and I agree with him on this one. Apparently, so did his publisher.
