UPDATE: All better now.
Just a quick note: I noticed that my blogroll, which is created automatically by Bloglines, has stopped working. I never turned off sharing, and now I can't turn it back on. But for some reason Bloglines thinks that I've disabled it. I sent them a note, and hopefully they'll help me get it back up and running. (A lot of programmers prefer to make rather than "buy." This is why; when something breaks we have to wait for someone else to fix it.)
