It seems like it's been out for a month now, but my new book--Where Good Ideas Come From: The Natural History Of Innovation--officially hits the shelves in a matter of hours. I worked harder and longer on this book than any of the six books before it, and I'm as proud of it as I am of anything I've written. I hope you all get a chance to pick up a copy, and to stop by one of the events on the tour, which starts today in my old hometown of Washington, D.C. You can buy the hardcover or the Kindle edition on Amazon, or here from Barnes and Noble. And of course it should be available at your local bookseller as well. I'll be posting and tweeting from the tour as the responses come in from the events and the reviewers, so stay tuned...
