I love the idea of many more posts in the comments section. I am not qualified to commit (but I won't let that interfere with an opinion" on the copyright portion of the question. I have always "heard" it was alright to post short comments from a book if proper credit was given. I don't think large portions of a book can be posted even with the proper credit, but that is just what I have been told by no qualified source, but it does make sense, I can see where gutting the info in a book could kill sells.
