Good news for those of us supporting MIT's OpenCourseWare project--it turns five today. It's good to see the project doing so well, and even maddening to think how long it's taking other universities to follow behind the trail MIT is blazing here. Of course, if you dig deeply into the site, you'll notice that not all these "courses" are very informative. Some consist of merely a course description and some project assignments. Still, the groundwork has been laid for a major contribution to public enlightenment.
