We seem to be having a problem with IPR #154 in iTunes. It hasn’t shown up yet even though we’ve dutifully uploaded the file several times. Libsyn, our trusted podcast hosting service, believes it’s a problem with Feedburner, a service through which we pass our feed to give us better stats. We are working on it. In the meantime, IPR #154 is of course available for download and playing right here on the blog. Thanks for your patience.
