Some large-scale research projects (and then another business trip) have kept the days long over the past few weeks ... and, as a result, the weblog quiet. The hours between 10pm and midnight should (hopefully) be a little less punishing in the coming month so I look forward to getting this back up to speed again. Thanks to those of you who emailed wondering what had happened (I confess I was less amused by those that politely asked if a certain Hurricane had been keeping me otherwise engaged!!)
