JohnTP.com quotes Everton who points out that following simple change that made the number of subscribrers to his comment feed jump overnight:
Find the following code in your header.php file:
<link rel="alternate" type="application/rss+xml" title="<?php bloginfo('name'); ?> RSS Feed" href="<?php bloginfo('rss2_url'); ?>" />
And under it insert the following:
<link rel="alternate" type="application/rss+xml" title="<?php bloginfo('name'); ?> RSS Comments Feed" href="<?php bloginfo('comments_rss2_url'); ?>" />
Now readers can easily subscribe to your comments feed.
