No idea what's going on here, but it appears that Airspeed is temporarily off iTunes. Some problem with WebPasties, my former RSS provider (who supposedly forwarded the feed over to Libsyn) when I requested it. Thought I had left these giys for good, but they apparently still have some hooks into my feed.
Anyway, it's completely gone from iTunes. Crap!
I resubmitted the podcast to iTunes a moment ago, but it will likelytake a few days to re-populate. In the meantime, please stay subscribed or re-subscribe. I'll try to get this fixed.
