My colleague Prof. Margo Seltzer has started blogging at http://mis-misinformation.blogspot.com/. She is joining the ranks of such distinguished Harvard Computer Science faculty who maintain blogs, including Michael Mitzenmacher, Harry Lewis, and Stuart Shieber. (Apparently, we have nothing better to do than stuff the interwebs with our crazed ramblings.)
Margo, welcome to the blogosphere. It's a lot like real life, only weirder.
