Thank you for the comments. Linxy doesn't just show you general Category news. You can create a very specific search feed: i) Pick very specific phrases/keywords which define your area of expertise, AND ii) select Categories of news sources. It is this combination (keywords AND filtering news sources), which creates a 100% relevant news search. If you setup both of these inputs well, Linxy will show you very relevant news only. You also don't need to sign-up to Pro (for emails), you can just bookmark the Linxy search url and visit it periodically.

You can browse some of the example searches shown on the first page to get an idea how the inputs can be setup for different use cases for various areas of professional/knowledge topics.
