Lots of data, but not much information. Before, tech books were an oasis because there wasn't much of anything anywhere. Now it is the opposite, too much of everything everywhere, I need someone to condense it down into a form I can use.
That can change; it depends on the publisher's perspective and goals. Our goal is always to publish fewer better books. (I stole that line from Prentice Hall. They forgot it years ago. :)
