> He kind of touches upon it, but there is a lot of value in being able to go into an interview and literally being able to say about a topic "I wrote the book on it." A lot of it depends on the publisher. If it is for example OReilly, I would be impressed. If it is Packt, I would not be impressed at all. Some publishers do a much better job of screening and providing editorial support and technical reviews so that if an author is published by them, I can have confidence that the author is a subject matter expert. Some publishers are little more than self-publishing and so I would not have confidence that the author was an expert.
