RSS is a useful way to keep track of news and blogs that you may have encountered before by "subscribing" to them. To subscribe to RSS feeds, you just need to find a blog or news site. Nearly every blog allows this, however some sites that aren't news sites or blogs will offer RSS feeds too. Though, these will need a button to subscribe. Or, simply look through the bundles on the Google reader.

I subscribed to a guitar bundle feed on the Reader, and really liked how it bundles together a bunch of sites that i already visit. I can really see myself perusing through the said sites for many hours, since I will occasionally get too lazy to visit every site, and sometimes forget to. Now that they're all in one place it's much easier to browse through the feeds. The inteface itself is okay, it gets the job done without being too flashy or overly simplified.

From the Mercury list I selected the city of my hometown, Cupertino, to recieve news for. I didn't have any trouble looking for RSS feeds on any other sites, because they usually make the RSS button very easy to see, either being placed at the top of the page or at the very bottom.
