not sure how you set one up, but an RSS feed is basically something that works with your browse in some cases, like i have an RSS feed setup with engadget, and everytime engadget post something new on their website, my feed gets updated saying its got 1 new entry i click on it and it shows me it, along with all the others, it shows it in like a list form etc, they are brilliant if you browse lots of news websites or a lot of blogs.
