It's not unusual for Google to acquire a company and make their flagship product completely free -- it has happened several times in the past with Keyhole (Google Earth), Picasa, SketchUp, and Urchin (Google Analytics). Surely it wouldn't stop there. Today Google announced that two previously for-pay services from FeedBurner are now completely free -- they are called MyBrand and FeedBurner Stats PRO.
MyBrand lets you take the FeedBurner service to a new level by using your own domain name as the feed URL. This has several advantages for all bloggers, but mostly for larger blogs or blog networks by allowing feeds to reflect your own brand. Instead of a URL that looks something like http://feeds.feedburner.com/zdnet/Google, it's now completely possible to have a URL like http://feeds.zdnet.com/Google without giving up the valuable information that FeedBurner provides.
The second feature they made free is the FeedBurner Stats Pro service. Here is how their blog describes the service:
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. You can turn this on by signing in to your account, navigating to the Analyze tab and heading to the FeedBurner Stats PRO section. Click the "Item Views" checkbox to activate these PRO features.
