My friends are doing so much writing and publishing these days that keeping track is hard. I think I may have to add a my friends write cool things feature to the blog. This week my friend Patrick Stewart has an article (complete with video) in the Washington Post parsing out the different kinds of smiles we see from our current presidential candidates. I’m always fascinated with body language and how we read it in politicians, so this one is of particular interest to me. Patrick’s a political scientist at the University of Arkansas. Link is here. He also has a book called Debatable Humor: Laughing Matters in the 2008 Presidential Campaign.
