I know there is a handful of people out there who subscribe to my RSS feed via FeedBurner (which is where the “Subscribe” button on the navigation bar pointed to until today). FeedBurner was bought by Google some time ago, and they are gradually getting around to migrating their service to a different platform. I’ve heard about occasional problems with that from different blog owners who have already been migrated, and, to be honest, I never really needed the additional bells and whistles that FeedBurner provides, some of which, I understand, are no longer going to be available on the Google platform anyway.
Therefore, the Subscribe button now points back to the original feed. I’m not planning to get rid of FeedBurner altogether, so any of my distinguished subscribers who want to stick with that may not even feel a thing, with luck. But if you notice a disruption in the feed at any point in time, please consider re-subscribing with the original feed.
