For what it's worth, sometimes I get very frustrated with HN, but I think the reason I keep coming back is because it provides me with a lot of context. Eg, I pick up a lot of information about techniques people have applied to certain problems, which I recall when I recognize a similar problem, and that gives me a place to start.
But I have had to cut myself off from a given community because my relationship became unhealthy with it many times. I get that.
