But I feel like it's a struggle to find the right content for you (reloading 'new' 20 times a day is a no-go). Even following your own conversations and threads is not super user-friendly - I discovered hnnotify to be alerted by email for each answer, which is working great.
Is there any way to ease the HN experience that are widely spread in the community? (automatic filtering of new posts by topics, mobile experience, ...)
A feature which has been very helpful a couple of times is the noprocrast setting, which you can get to boot you off HN for a while if you spend too much time here.
If you click thread at the top it's not hard to see if your recent comments have replies.
Sometimes I look at https://hckrnews.com/ which just shows the recent top stories in chronological order.
Also see this github page about undocumented HN features https://github.com/minimaxir/hacker-news-undocumented
If you want to add to HN, go to new and upvote good stories. Go to ask and answer questions. Go to show and give people feedback. Submit fascinating things. Write awesome things yourself and submit them. Teach us something. (Ask not what HN can do for you etc) Good luck.
Maybe the place to start is with RSS modulo grep/sed/awk.
