I have a massive backlog of posts I want to write, sitting in my inbox. Topics include is globalization good for the middle class, the crazy online course boom, and, of course, the rise of the drones. But I haven't written any of them because random other things are eating all my time. I expect all three of these topics will do me the favor of hanging around for a while, until I'm ready to address them, and in the meantime I'll let them percolate.
