The newest IE 7 will also have RSS support built into the browser so you will be able to read (or subscribe) to feeds. Other ways you can keep tabs on various feeds is to subscribe to a feed service like bloglines, my yahoo, or Google Personalized Home. Then you just add the URL of the feed (for example http://www.ahfx.net/rss.php) to the feed reader and it will automatically compile the "newest" info for you and keep track of what you have already read.
A simpler way to "subscribe" to a feed is to click on "subscribe" buttons (like the ones found on the right hand side of this page) for common feed aggregators like bloglines.
