I don’t know how I failed to deal with this at the appropriate time, but basically Google bought FeedBurner, I didn’t take care of business, and now I can’t access my FeedBurner account.
So I’m turning off the FeedBurner plugin, which will break everyone’s RSS subscriptions. Good news! You can resubscribe using this feed: http://www.megantaylor.org/feed/.
My apologies for the inconvenience.
