Personally, I think RSS is one of the greatest inventions of the World Wide Web. A tool that comes in handy in today's saturated sources of information. The main advantage is that you don't have to remember links or go to different sources of information, all the news comes directly to your mobile, tablet or desktop when they are available.
Some people thinks that this icon means wifi available
Nooooo!!!!. It's an RSS icon but...
What is RSS?
RSS (RDF Site Summary or Really Simple Syndication) is a web feed that allows users and applications to access updates to websites in a standardized, computer-readable format. Subscribing to RSS feeds can allow a user to keep track of many different websites in a single news aggregator, which constantly monitor sites for new content, removing the need for the user to manually check them. News aggregators (or "RSS readers") can be built into a browser, installed on a PC, or installed on a mobile device.
How to use it?
The Dynatrace Page for RSS feeds is https://www.dynatrace.com/news/category/
Here you need to copy the link that is in the boxes and paste it on your favorite news aggregator. Here you have plenty of options NetNewsWire (free and open source for Mac/iOS), Feedly (with options for free and paid for Android, iOS and web) among others. I've used the latter for the example. Each client has different options, fonts, styles and options to share among others.
After copying it, you can paste on the option to add feeds:
Then you can add it.
and organize them in folders
After doing this, voilà. You have a single point for all your news and it's easy to share or do other things with it.
I hope this helps you as it helped me.
