Feed showing no items

Hi,
I’m having some problems getting my feed to work. When I try to add my blog (http://siopaeile.com/blog/) to Google Reader, I get the following msg “feed/http://siopaeile.com/blog/?feed=rss2″ has no items.”
This is the code that shows the default wordpress rss link on my home page
<li><a href="<?php bloginfo('rss2_url') ?>" title="<?php echo wp_specialchars(get_bloginfo('name'), 1) ?> RSS 2.0 Feed" rel="alternate" type="application/rss+xml"><?php _e('All posts', 'blogtxt') ?></a></li>

Perhaps this is the reason why I’m not getting picked up on technorati either. Would appreciate any advice on this as I don’t know anything about php.
Oddly, my feedburner feed seems to work, despite being based on the original feed which doesn’t work. thanks
