We’ve changed the content-delivery architecture for IT Conversations, and one unpleasant side effect is that the URLs for our audio files have changed. (Hey — we warned you not to link directly to the MP3s!) Unfortunately, this also means that you may receive duplicate files if you’re subscribing to our RSS feeds. It’s a one-time problem, and you won’t be receiving duplicates on an on-going basis, however. Only the most-recent 20 URLs exist in both the old and new forms in the feeds.
