According to the FeedBurner Blog all FeedBurner accounts will receive a free upgrade to FeedBurner Stats PRO as well as free access to the MyBrand Service. I don’t think it’s a coincidence that this free offering is happening just weeks after Google purchased FeedBurner.
MyBrand
“The MyBrand service (also PRO-level) is located under the “My Account” tab after you’ve signed in. MyBrand lets you maintain consistency between your feed address and your hosted website’s domain, if matchy-matchy is your thing.”
FeedBurner Stats PRO
“PRO is feed analytics taken to the next level. You will now have access to the number of people who have viewed or clicked individual content items in your feed and “Reach,” which estimates the daily number of subscribers who interacted with your feed content.”
