Hellbound Alleee and the Ebon Muse have posts up on the Blasphemy Challenge, Alleee's post is particularly thought-provoking (while it's silly to imagine that a project like this can be an entirely non-group endevor, it's also worth remembering that when someone says something on one of those videos, they aren't speaking for some corporate entity.)
Brian Flemming also has an update, which includes a link to a New York Times article on the challenge. This is the best sort of coverage you could ask for, I think--you get mini-profiles of two atheists, and the people they talked to on the other side are rapture nuts who declare, "We are not dealing with human versus human."
Also, the RRS has teamed up with the American Humanist Association on a parallel project. I'll try to get a submission to that together sometime soon.
