There's a lot of content on the Hub, and one of the best ways to keep up with it is to subscribe to RSS feeds.
WITNESS provides RSS feeds of all content contributed to the Hub according to Content type, Country, Region and Issue.
RSS stands for "Really Simple Syndication" -- it's a format for distributing and gathering content from sources across the Web, including newspapers, magazines, and blogs.
Web publishers use RSS to easily create and distribute news feeds that include links, headlines, summaries and sometimes videos.
RSS feeds are read with "News Readers" or "Aggregators". For more information, please read the wikipedia article on aggregators
