Feedburner Circulation returns the number of subscribers for a Feedburner feed. Supports multiple feeds and reduces API calls by saving to your WordPress database. Also, if the Feedburner API is down, the plugin will not throw xml errors when the http_code is something other than 200.

You can use the function <?php feedburner_circulation_text('feed_id'); ?> in your template files.
