Aha, I just figured it out. I’ve done some work disentangling my email streams so that in certain contexts I could actually read one email without having three new ones arrive during the same time. Then I want out of town for a few days. As a result, I never saw my email to post information about today’s Atheist Talk Radio show.
Put PZ did not screw up his responsibilities to the cause this week, so go read his notice. And turn your radio on!
