Methods and tips on mindfully pruning of information intake

I'm working on pruning the sources of information that come into my Readwise/Read Later feeds down based on usefulness/actionable in my life and quality. My priorities are for data sources to expand my 'reality tunnel', to provide unique insights (not an echo chamber), and to remove a lot of the 'noise' of the day-to-day information overload. I'm considering what those sources might be. If you have a moment, I'd appreciate your thoughts, advice, and links to any writings or videos that speak to this similar goal and how others have done it. Thanks in advance!

The noise is deafening, but I promise to focus on the high-value signal.

I'm seeking to reduce the noise, and increase the signal of my Reader feeds.
