In honor of the current three day weekend, I shall not post more parts of my current tutorial until Tuesday. I am ready to go, but I suspect my readers have other things to do. Apologies to the overseas contingent, for whom this is just an ordinary weekend. I shall try to find something suitably trivial to blog about, such as, for example, the rumors that Michele Bachmann's husband -- the "therapist" who works to "cure" gays -- is himself deeply closeted. Clearly, the excitement of The Fourth of July has addled my brain.
