By popular demand this blog is back in operation, though with only limited participation in the future from me. Past contributors to this blog have decided they are willing to shoulder the responsibility of maintaining this blog, namely, DaveScot, Bombadill, Crandaddy, and Gumpngreen. Unlike in the past, when they were limited to commenting on my postings, they now have full posting privileges. They will be in charge of the day-to-day business of this blog, everything from keeping it interesting to approving comments to booting recalcitrant commenters. Of these four, DaveScot has been the designated blogczar — the buck stops with him.
