Concerning the FTC thing on bloggers who post reviews, first up I'm Canadian so there's that. Plus, I've only ever been offered three things to review for free (that I can recall) and only took up the offer once. The other two I declined the free version to pay for it, mostly for wanting to support the creators of those projects. And for the one time I did mention being given the book to review so there.
I'm actually surprised that I was offered anything for free but I guess even a blog that's got as few visitors as mine could be a potential place to build up steam for a book.
