Some years ago I used twitter as a news aggregator, I followed lots of people who posted good articles and news. This changed over time and my twitter feed became lots of comments and nonsense :)
So I switched to a old, but very good way of reading news: RSS
I currently use the app Flym on Android for reading rss feeds.
My current rss feeds sorted in alphabetic order:
Local News (Freiburg)
Politics
Technology
