What is RSS?

An RSS feed is provided by a publisher who wants to allow their readers to easily get updates when new content is added which falls within the scope of the feed. Instead of requiring readers (or even worse, software) to constantly check a web site and look for changes, having the RSS feed URL gives readers the ability to see updates in whatever RSS reading software they choose.

So RSS provides a single URL that summarizes content–maybe blog posts, search results, tweets, or videos.

RSS is an XML-based format that allows the syndication of lists of hyperlinks, along with other information, or metadata, that helps viewers decide whether they want to follow the link.

This allows peoples’ computers to fetch and understand the information, so that all of the lists they’re interested in can be tracked and personalized for them. It is a format that’s intended for use by computers on behalf of people, rather than being directly presented to them (like HTML).
