I have to say, this exchange has been mad interesting. We're winding it down, and I'll try to get my final thought out before I head to Austin TX this weekend for SXSW Interactive.
We've had a few other folks chime in with their own video responses. I'll continue posting those and trying to centralize them at http://letstalkaboutrace.wordpress.com so there's an archive of this experiment.
