RSS (Really Simple Syndication) is a web feed standard, which lets you view articles from various websites in a single app of your choice. Instead of having to visit various websites for your daily news, all of them can just be aggregated in one app, and not on that opens the links, it formats them how you like it.
It's an open standard and a backbone of the free internet, and this blog offers its articles in their entirety on its RSS feed, which you can find at /rss.xml, or by pressing the button below.
Here are some of the free and open source RSS Readers I recommend.
Paid/ad-supported apps like Reeder and Feedly do the same too.
