Query: Evergreen topic backed with real research

Excellent, well-researched examples of what really makes an idea stick. I read a copy from 2008 and the concepts of what makes an idea stick is as relevant now as it was 2 years ago--and it will continue to be a worth-while read years from now. Made to Stick isn't just a compilation of opinion; it's backed with the years of post-grad research that both Heath brothers produced from their work in the last 10-15 years.
