I now make an active effort to read the article as I discover it - the point being (for me) that if I'm in the process of "discovering" an article, I'm not "working" on anything else that leads me to have to save it for later -- I'm in the zone, read it and not worry about coming back to it! It's been quite a pleasant change. I don't read as many articles as I'd have saved before, but I'm ok with that!
Now I read things on an "as needed" basis: I find and read articles as I need them, for instance if I'm learning about Kubernetes that's when I'm going to go and read 10+ things in one sitting.
Another thing I realized: If I found it once, I can find it again... When I need it. The article isn't going anywhere.
So take away is that don’t get frustrated by ever growing read it later list. Think of it as way of creating your local searchable crawl of pages that matter to you.
