The basic version of the FeedBurner RSS service was always free, but there were some advanced features you had to pay for. Now that the tool’s been acquired by Google, FeedBurner is completely free (and existing pro account users will not be charged from this month onwards). The features made free are:

* The statistics of how many people viewed, or clicked an individual post of your feed (this was part of what FeedBurner called “TotalStats”)
* The “Read” stats, which are an estimation of how many subscribers interacted with your feed on a given day
* A feature called “MyBrand” which allows you to set up a FeedBurner feed right on your domain

The FeedBurner blog writes, “We suspect this will be welcome news to the 450,000+ of you using many of our other free services, but understanding that your feed is your feed, you will need to activate these newly freed-up services in order to partake in their awesomeness.”
