Al Essa, the CIO of the Sloan School of Management at MIT, has not one but three public blogs: Tatler , described as “A personal perspective on intellectual history, aesthetics, political economy, and arts and letters”; The NOSE (Navigating Open Source Elearning); and Rude Mood, about running. I’m not sure that three complete independent, separately branded blogs aren’t overkill, but I guess it keeps things from getting confusing. A belated welcome to the blogosphere, Al.
