Dear Liquid Gear
I understand about the Amazon policy. Although feedback about the book right here on MR would be great too.
The giveaway days for Boomerang are over. As a promo tool I have found it to be something less than effective and my guess is that 99% of the thousands of copies given away have never been read and likely never will be.
If $2.99 in completely extraneous funds ever fall in your lap, I hope you will consider squandering them on Boomerang! And if so I would very definitely like to hear what you think.
