SEASONAL ADJUSTMENT. It's not for the faint of heart. But it's a phenomenon, and it's worth thinking about. Deionychus suggests there is a holiday lull in blog traffic. A correct seasonal adjustment is likely to be difficult as many writers as well as readers took a break. My own counts suggested fewer than 20 readers per day during the Christmas closure. I resumed more-or-less regular posting after January 2. On Monday the 6th I had 50 visits, many arriving via one or another of the academic weblogs. Some of those have gotten back to more or less regular schedules.
