Query: Did the author write all these positive reviews?

I had great hope for what what I could learn from this book. But it's mostly on and on about little useful how to stuff. At COMMON recently I strolled past the (new publisher cause they said the original went Bankrupt) publisher's booth and they were joking about writing online reviews and testimonials! They must not have known I was there. I looked over his new book hoping it would address the important stuff but it's wasn't much better and it's too expensive to make this mistake again.If it's the boss's money what the heck. If it's your money then keep looking!
