Seth Godin is one of my favorite marketing gurus. I met him at a TED Conference a few years ago http://www.ted.com and follow his blog on marketing and social change http://sethgodin.typepad.com
Last year he offered a wonderful book, a free eBook featuring more than 70 big thinkers offering ideas for us to think about and share as we navigate making the world a better place for everyone.
Great summertime, anytime reading! Enjoy and share What Matters Now! Cheers, Lori
