How to export feed agregator list and setting as feature?
I have achieved this using aggregator_save_feed() function in hook_install() or hook_update_N() of my custom module. It's not a feature but there is not much difference.

Example:

/**
 * Implements hook_install().
 */
function MYMODULE_install() {
  $feed = array(
    'title' =&gt; 'Business',
    'url' =&gt; 'http://feeds.bbci.co.uk/news/business/rss.xml',
    'refresh' =&gt; 3600, // Update interval in seconds
    'block' =&gt; 5, // News items in block
  );
  aggregator_save_feed($feed);
}
