I had that option for a while and got annoyed by it. I turned it off, because it was often activated right before submitting or commenting (I know it gets saved and won’t get lost but still).

What I do now instead: Before picking up the phone/going online, I force myself to give myself a short reason what I want to do and why. This loop helps me to avoid 50% of pick-ups, which is not perfect, but not bad either.

The fact that HN gives you this option at all, to my mind, sets it in the very unique category of self-aware information sharing communities/platforms. Reddit has subs that focus on productivity and discuss addiction to Reddit itself, sure, but they seem to be going down the same path of catering to addiction now.. deleted Reddit entirely in lieu of HN recently and it's been fantastic.
