Query: Worthless Travel Handbook

I purchased this guidebook because my much trusted travel store 'highly recommended' the book. I have traveled all over the world and I have never been more frustrated, and annoyed, at a guide book than I am with this one. It has been completely worthless - from a useless and incomplete language section, to poorly edited maps (or no maps given), recommended Pousadas with no address and no phone number, to sections that go on-and-on about what to do while in a town only tell you to hunt down the local paper (which is in Portguese)to find out where to go for a "do not miss" experience. A three year old Lonely Planet has been far more useful and accurate than this latest edition. My question - who writes and edits for Footprint and what are they smoking?
