So I finally added, on the left side-bar, a list of "recommended" blogs, i.e., blogs I read more-or-less irregularly, but which are informative or at least fun.  I want to call your attention, in particular, to the fact that Thomas Nadelhoffer, who has done a spectacular job keeping this site interesting and educational all summer, has decided to start his own blog.  Professor Nadelhoffer will be here till the end of August, and I am hoping he will come back for a week or a month in the future, as his schedule permits.  But do check him out at his own blog site.
