You need an RSS feed reader...some browsers may have them built-in, e.g. Firefox ( http://johnbokma.com/firefox/rss-and-li ... marks.html ).

An easy way to consume news, lists, forums, etc.

For you Mac users there is a great freeware app called NetNewsWire that is really the standard by which RSS feed readers are judged. I use it daily. It is so much easier and more efficient than just using the browser. The readers in Safari and Firefox aren't that good, actually. Here's the link for NetNewsWire:

Different strokes, I guess -- personally I am a resolute devotee of Google Reader, which you get automatically if you have a Gmail account.

Other big names to consider include Netvibes and Bloglines. A fairly competent RSS reader has also been integrated into the "new" AJAX version of Yahoo MaiI. Regardless, I am totally convinced that nearly any dedicated RSS reader, whether web-based or in a desktop app, will easily outperform the built-in RSS interpretation abilities of Firefox and Safari.
