In your template index.php file, paste the following into the head section and change "joomlabloggerfeed" with your own Feedburner ID (ffid).
<link href="http://feeds.feedburner.com/joomlabloggerfeed" type="application/rss+xml" rel="alternate" />
When users now click the RSS icon in the browser, they will get the choice of choosing either the rss feed, the atom feed or your feedburner subscription page, giving you even more subscribers.
You can try it on my front page.
What About "Show a Feed Link"?
You might be tempted to disable the "show a feed link" in the home page menu item. However, if you do so, the RSS feed for the page will not be available anymore, and Feedburner will be unable to update your feed.
Comment Rules: Critical is fine, but if you're rude, I'll delete your stuff. Please do not put your URL in the comment text unless it's relevant to the post and please use your PERSONAL name, blogger name or initials and not your business name, as the latter comes off like spam. Have fun and thanks for adding to the conversation!
