Erin McKean: Redefining the dictionary (sorry. I played with the HTML long enough to get her presentation embedded here, but can't figure out why it locks up 14 seconds in and loses the sound. Just click over there (Warning: it's a 16 minute speech))
I don't know that I concur with everything she says, but I certainly agree that language is an evolving tool, and that our record of it should be as complete as we can possibly make it.
That's why I join her in loving the Oxford English Dictionary above all other dictionaries (except maybe the Funk & Wagnall's my paternal grandmother gave me on my eleventh Christmas).

And yes, it's the word-of-the-day from the OED online.
