I'm currently reading Rework, by Jason Fried and David Heinemeier Hansson, which is a very good book. I properly like it. Also just starting Advanced Google Adwords by Brad Geddes, because I simply can't get enough of Adwords books.
Loved this book when i read it, the folllow up, New Market Wizards is also very good, although not quite as good as the original. You'd probably enjoy Edwin Lefevre's Reminiscences of a Stock Operator.
I haven't read "Getting Real" you see, just bumped into the book on Amazon a week or so ago and thought i'd give it a go. I really like it though, but then i never bought it to read as something tech related. I bought it based on just general business, which was shown, i felt, from quite a nice contrarian angle.
Obviously "Getting Real" is going in the shopping basket now.
