To the fraction of a person who cares: the one page on the Internet that links to my pre-MT blog is now correctly redirected to the equivalent items in the MT blog. (Originally, I used a Redirect directive instead of a Rewrite. After I reinstalled MT and switched to a MySQL database because the Berkeley DB was corrupted, I just put the archives at a compatible URL.)
Oh, and Google finally indexed my website again, so searching for the title of the weblog now yields the weblog as the second result (the first result is still Blogshares, for some reason — I don’t play, but I claimed my blog anyway).
That is all. Please resume your regular indifference.
