If you have even an inkling of an idea of doing a startup (or more traditional software enterprise), you must read this book.It's practical. It's real world tested.I've followed Rob's blog for years. Rob knows what he's talking about. Rob details various business ventures and what has worked well and not so well.Great easy reading with no filler.  Unlike other business books that are loaded platitudes and extra words, this book gets right to the point.
