Query: Poorly written

This is one of the most poorly written technical manuals I have ever used. The tone of the book is patronizing and the cost too high. The three book series (user manual, tech manual and "loaded" version) should have been condensed into one clean book. The print quality is really bad, it looks like it was printed on a very old laser printer. I can't see how the author sleeps at night knowing this garbage is going out with their name on it.Where is O'Reilly when you need them?
