All Feedburner feeds need to move to Google accounts by the end of February, and I’ve gone ahead and made the switch. I don’t expect any interruption in service, but you never know. According to the FAQ, the old URLs should redirect to the new location, so if you’re already a subscriber you shouldn’t need to do anything.
For the record, the canonical feeds for this blog are http://feeds.doughellmann.com/DougHellmann for all posts and http://feeds.doughellmann.com/PyMOTW for just the PyMOTW posts. Those URLs have not changed, so if that’s how you’re subscribed you should be good to go.
