Excuse the silence. In light of past gaps, I thought it important to say that Scott's on the road and I'm hard at work on a piece you'll see at BP soon, as well as two other research projects. More here soon ... and be sure to follow this space next weekend. I'll be in Anaheim "liveblogging" for the Winter Meetings.

Someone suggested I do open threads. No. Not gonna happen. What I wouldn't mind doing is guest submissions. If anyone has an idea, you know where to send it. Don't make it too short and don't take it personally if it's not good enough.
