What is an RSS feed?
How do you know if a website has updated information? One way is to check it regularly for new content; another way is to let the website automatically provide you with links to this content. This can be done with RSS feeds. An RSS ("Really Simple Syndication") feed allows a website to alert you as soon as new or updated content has been added.
Feeds can be read by special programs such as Google Reader, a popular and free web-based reader. But current web browsers all have built-in RSS capability, making them an easy way to access RSS feeds if you are new to the technology. Instructions follow below for Firefox and for Internet Explorer; instructions for Opera and for Safari are available at their respective websites.
