RSS, Feeds and Atom can sound confusing but the idea is very simple: make it easy to follow updates from a web site. There are two parts to using an RSS feed:
1. RSS Readers are the main tool you'll need in order to keep up with RSS Feeds. They turn the technical mumbo jumbo of a feed into a format you can read and follow. There are plenty of RSS Readers to choose from and we gladly recommend Google Reader or Bloglines.
2. RSS Feeds themselves are simply a file format that makes it easy for Feed Readers to consume. They are commonly called Feeds, RSS, RSS 2.0, Atom, Syndication, etc. They are also often associated with the orange icon feature to the top left on this page. The size and shape my vary but it's generally something like that. Wherever you see this image or terms there is usually a Feed you can follow.
Here are our feeds in the two most popular formats:
You only need to subscribe to one as they both contain the same data, the format is just a matter of preference. So go get a feed reader and start keeping up with updates even faster!
