You probably already have access to a feed reader. There are both mobile feed readers, desktop base feed readers and web based feed readers.
Mobile devices such as smart phone have an app for reading feeds. Take a look in your phones app directory and search for RSS reader. There will be a number to choose from.
Another way to read rss feeds is by a web based feed reader. Services such as Bloglines, MyYahoo, and MyMSN all allow you to collect feeds from various sites and go to one site to read them all. The advantage of using a web based service is that you can read your feeds from any computer and when you change machines you still have all your feeds in one place.
Client based feed readers – programs that you add to your home or work computer that allow you to read feeds are available. Microsoft Office has a feed reader in the left side or your folders look for the folder marked RSS Feeds and follow the get started instructions. On the Mac mail also comes with a feedreader.
