I didn't realize that if I upgraded Blogger's layout (which I needed to do if I wanted the Twitter feed back), that I'd have to re-do all the work I did yesterday. Crap. If I'd known, I would have just upgraded yesterday & done it in this format from the start. Ugh.
Also, I hate the way it looks, and I'm not sure I'll be able to sort the blogs into categories. I preferred being able to mess with the HTML. I'm not exactly a high-powered web coder, but I had enough knowledge to get what I wanted. Thank, Blogger. Thanks a lot.
