Wow. You might think the JetPack team would have cooked something like this up, but no. Simple Feed Stats is from Perishable Press (you know, Jeff Starr). It’s a great WordPress based solution for tracking feed usage and subscribers. It just came out, so it might be a little rough, but if you dumped FeedBurner or are thinking of jumping that burning ship, well, I suggest this. Jeff knows exactly what he’s doing with WordPress.
Simple Feed Stats is a free WordPress plugin that makes it easy to track your feeds, add custom content, and display your feed statistics on your site. Simple Feed Stats (SFS) tracks your feeds automatically, and provides a wealth of tools and options for further configuration and management.
