RSS feeds, sometimes known as “syndicated feeds” or “news feeds” allow you to subscribe to content that is published on a site without having to go to the site to check if new stuff has been posted. To subscribe, all you need is a news aggregator service/software, which collects all of the feeds and presents them in one place. You check your aggregator every day instead of going to several different sites.
RSS readers can be applications you install on your computer or sites that you log into. My favorite is bloglines. Learn more about RSS in plain English.
