OK, so… I never heard back from the folks at FeedBurner, so I just went ahead and set up a new RSS feed. If you are subscribed to the old FeedBurner RSS feed, you will need to update your clients to the following address:
http://feeds.feedburner.com/jimcofercom
If you were using the “direct” feed, you will need to upgrade your client to the following address:
http://jimcofer.com/personal/?feed=rss2
Please choose one of these two, as the old RSS feed is dead as of today.
