Change of venue: update your links 

I've taken the plunge and moved to TypePad. I'm still experimenting with the layout, the link options, and the possibility of importing all the old posts from here, but come over and check out this blog's new home anyway, and tell me what you think of the three-column layout and the new color scheme. Whee! Excitement! And now I'm going to go avoid grading. Yet again.
