What is a feed?
Feeds allow you to easily see when your favourite websites have added new content. They allow you to get the latest news, publications, jobs and actions all in one place and as soon as it is published, without having to visit the websites directly.
Feeds are also known as RSS. There is some debate as to what RSS actually stands for, but most people go for Really Simple Syndication. In essence, the feeds themselves are just web pages, designed to be read by computers rather than people.
