@Tink1113 It’s a way of, well, feeding website content into an easily accessible place.
It’ll basically direct all of the articles from websites you pick into basically an inbox.
I suggest just giving it a try, head on over to reader.google.com if you have a google account, and start adding subscriptions by clicking “Add a subscription”.
Alternatively, go to a website you like, and look for an RSS feed button. It’s an orange square with white lines.
One website with them, for example, is Fluther. Just scroll down to the bottom of the page, on the right side.
I love rss feeds. I use google reader. I’ve got feeds for Blizzard games, NCSoft games, TF2, most Gawker sites, and a few other various sites.
