If I read only front page I would miss tons of content.

For long time I used Hckrnews with top 50% option, but I was still missing some content interesting for me. https://hckrnews.com

Few weeks ago I switched to Serializer (just HN option) synchronized between PC/mobile and I am happy with my choice, I see much more posts, but not all new + I can easily mark those I checked as read. https://serializer.io

Once a day I check also top 24h submissions here, if I haven't overlooked something: http://besthackernews.herokuapp.com/
