For those of your wondering how many subscribers you have to your blog feed, which information visitors most frequently visit on your blog, and various other blog related statistics, google has an application for this as well. FeedBurner is an application recently purchased by Google, which is relatively user friendly and since it was purchased by google has become free. Currently, users merely have to have a google account to use the service.
FeedBurner claims that it's main benefits include: allowing users to analyze their blog traffic, optimize content format of blogs, allows further blog publicizing, and gives users the option of making money through ads. The FeedBurner service is also available for podcasts and corporate websites.
I am sure there are similar applications to FeedBurner out there. But after searching through various other applications, I found that a good portion of feed analysis tools require subscription or are not overly user friendly.
