If you are using the Firefox web browser, look for the icon 
. You can usually find it in the address bar above, as well as in the side bar under Subscribe. (It may be a different color, but the design is usually quite similar.)
Click on the icon, and it will give you the option to “Add Live Bookmark!”
I like to add my “live bookmarks” to the a folder in the main “Bookmarks Toolbar Folder.” Then I can just click on that folder and slide my pointer down over the desired feed (“live bookmark”). The feed will then expand to show all the lastest posts on that blog or RSS-enabled site. I can click on any “headline” and go right to the posting!
There are other special programs that can collect your RSS feeds, but I like the convenience of reading them right from my Firefox browser.
