The Search is an interesting book by John Battelle covering Google and similar companies, how the web is evolving, the business model behind it and the like. Subtitle is "How Google and Its Rivals Rewrote the Rules of Business and Transformed Our Culture". I've read only the first chapter so far, but find it quite interesting... will keep you posted how I like the remaining material. It is astonishing to think of the world before we had search engines in general and Google in particular, and that was only a few years back!
