Really Simple Syndication (RSS) is an XML based format used for content distribution and syndication. Subscribing to RSS Feeds allows you to receive custom, up-to-date information from your favorite online content sources without having to regularly check the site for updates.
How to Access RSS Feeds
Installing a news reader that displays RSS feeds from the websites you specify allows you to keep up to date with all your favorite content by checking the RSS feeds you have subscribed to and displaying new items from each feed. Instead of downloading a dedicated news reader, you can also use a web-based news reader.

YouTube offers several RSS feeds for categorized groups of videos (such as recently uploaded, top viewed etc) as well as customized feeds for users and tags. To subscribe to categorized groups of videos, simply click on the orange 'RSS' button next to each feed. To create custom feeds, specify the tag or username you wish to subscribe in the URL as described below.
RSS Feeds for Tags and Users
To create an RSS feed for your favorite tags or users, simply enter the tag or username as specified in the below URLs. You can then add this URL to your newsreader. Please note, you will need to create a feed for each individual tag or user you wish to subscribe to.

feed://www.youtube.com/rss/user/[insert username here]/videos.rss
