My reading is usually "all over the place." I read blogs and the studies/articles to which they link; i read vintage fiction for relaxation; i read esoteric material from respected sources; i read a few modern writers of nonfiction; i read LOTS.
One thing i resent, however, are the books that say the same friggin' thing over and over and OVER, so as to have enough material to fill a book, and it's been my sad experience to do that lately. "Fiber Menace" and "The Carnitine Miracle" fall under this heading. Read the website, and google the subjects, and you'll waste less time and money.
Then there are the ones which should be considered primers for the uninitiated. The reason i HAVEN'T ordered "Primal Blueprint," "It Starts with Food," and a number of others is, i don't need to be told the basics AGAIN. I've skipped so many paragraphs in "Primal Body, Primal Mind" after reading the first sentence.... The "body" half of the book told me almost nothing new, and enough that i disagree with, that i'm not sure i'll be able to believe what i read in the second half (the "mind" part), about which i know significantly less.
I haven't finished "Excitotoxins" yet, and it's been months. It is singularly unreadable, even though he presented plenty of material. Not so "Good Calories, Bad Calories," which some people complain about due to the large amount of material -- some authors CAN, and others CAN'T write worth a damn. I "breezed" through GCBC in a very short time, like the first time i read "The Lord of the Rings." Nonfiction doesn't HAVE to be dry and unappealing.
I suppose i should go to amazon.com and leave reviews, though i can think of a thousand more attractive ways to spend my time. Before i buy books, i generally read the highest and the lowest reviews, to get a hint of how they please various audiences -- that's one of the best features of the site. If only there were a ranking system: THIS is a 101 sort of book, and THAT is a 301....
I wonder if you can sell back a Kindle book?
