One of the consequences of IT Conversations leaving Gigavox Media and returning to the Conversations Network fold is that eventually we needed to remove 'gigavox' from the feed name. Unfortunately, Feedburner will only forward a feed for 30 days and many RSS readers don't seem process permanent redirects well (change the URL permanently, not just follow it).
As a result, you might not be seeing updated IT Conversations shows in your favorite podcatcher. So, take a few minutes and make sure you're using this URL in your feeds:
I checked the feed URL on my copy of iTunes and it seems to have dealt with the permanent redirect just fine (click on the "i" icon at the far right of the podcast name in iTunes to see info related to that podcast).
