Thanks to everyone who emailed me about the title change.
I decided to go with just my name. It's the least likely to become an annoyance of all the options I was thinking about.
Side benefit: in the process of adding in a "formerly..." message, I finally figured out how to add a little slogan under the main title in the Blogger template code. So whenever I get bored of "Amardeep Singh" I can just change the sub-title and put out a new message to amuse myself and hopefully one or two others.
So I can still use "Civilization and Disco," "The Whale," and, er, "Leonine Illumination" for a little while, without having to commit... Maybe a weekly rotation...
