There is no need for a full RSS reader in IE. However the Live Bookmarks feature in Mozilla Firefox is simple and effective. It creates a special folder in your bookmarks list and adds a separate link inside that folder for each post in the RSS feed.
If there is an .rss file then this icon shows the .rss reference is pulled from the META tag
Eg.
<link id=”RSSLink” title=”RSS” type=”application/rss+xml” rel=”alternate” href=”http://blogs.ssw.com.au/andrewweaver/rss.aspx”></link>
