I used to sign up for an HN newsletter that'd only show the top posts. I thought that was an effective way of pushing only the best content to me every few days. Realized later that I enjoy reading a some articles that didn't get a lot of upvotes.
I also tried to create an open google doc where a small group of friends could share links to articles they found particularly noteworthy. Participation was 0, so I gave up and now just store interesting articles in my bookmarks folder. Messy.
