Well, I'm having all sorts of problems with this blog this week. The Comments service, Backblog, is acting up big-time and also causing very long page-loading times, so in my attemts to turn it off I messed up the formatting so that now the page extends past the right edge of the screen, and the left margin for the posts gradually shifts to the right as you descend the page. I apologize profusely for all this and hope to find some time soon to find what's causing all this.
