Feedburner.com did some nice changes. The new design of your administration menu is great and not that full as it was before.
I do like the “personalized Feed”, which informs me about the status of my feeds, wether feedburner has problems while reading them or not. If you don’t use Feedburner yet, read the features and give it a try!
If you are using wordpress, Orderedlist has a plugin for you
