Been a HN user for 6+ years and after all these years HN is still pretty much the only feed I check on a daily basis. (not on Facebook so my example may not be very relevant)

The thing I love about the experience can be summed up as: - no click bait headlines - no endless "engagement", notifications, round navigation and noise (incredible quality of content curation) - amazing community (comments are often more insightful than the source)

Basically there comes a moment when you're up to date - reading done - and can carry on with life afterwards.
