News feeds are an easy way to keep up with websites without having to constantly visit them. When a website is updated, that site's newsfeed can notify you and give you a link to the new content.
All you need is a feed reader (also known as an "aggregator"). Most current web browsers have feed readers built in. You can also use web-based readers or dedicated software.
News feeds on this website are linked using the industry-standard orange icon.
There is a "feeds" module in the right-hand column of most pages, which lists a selection of feeds.
