Can't believe I missed it completely, but lexicographer Ben Zimmer just appeared on Wisconsin Public Radio with Ben Merens. (He also interviewed some of the Wisconsin Englishes Project folks, just as they were getting that project up and running.) The link is here.

Well, we've got Chanukkah, Solstice and Festivus behind us now, and Christmas is here, so it's just Kwanzaa to go, then New Year's.
