FeedBurner is going into maintenance mode July, 2021
Beginning in July, 2021, FeedBurner will go into maintenance mode. Existing feeds will continue to serve indefinitely, and existing users can download past usage statistics and email subscriptions. Users will still be able to create new accounts and burn new feeds. However, some existing features, like email subscriptions and detailed analytics, will no longer be supported.
I am investigating alternatives. In the meantime if you find AWOL to be a useful source of information, please add it to your feed reader. (I use Feedly).
