It is with incredibly mixed feelings that I pass along to our readers that Professor Katie Porter is leaving our blog. Katie was one of the original bloggers on Credit Slips back in 2006. There were a number of us who were working together in an intensive data-collection phase of a research project, and a blog was a great way to have some intellectual interaction that was more than how to word a survey question. It worked and somehow the blog stayed around. Katie's posts are insightful, thought-provoking, and witty.
