Keeping up to date with information and news with RSS feeds
What is an RSS feed?
An RSS feed is a clever way to keep up to date with a source of information. Basically, an RSS feed is an automatic system of keeping up to date with a source of information. Sites that have RSS feeds automatically update these when the publish a new article/post. The information in the feed is standardized so that it can easily be read. RSS feeds is the fastest way to follow the headlines.
The reader i use is just Firefox, which has native support for RSS feeds. The screenshot below is a picture of me viewing a newspaper's feed in Firefox.

But which feeds to follow?
Below i will list all the feeds that i currently follow. The list is slowly growing. I will also put a small explanation of the website in question. Naturally, i don't read all the news on all of these. I look closer at the headlines that sound interesting.
