(Unless the tangent leads toward a mind-killing subject like politics. I'm 100% behind you on applying careful consideration before making a tangent from a technical topic to an emotionally-charged one; people see that kind of subthread and never even make it to the rest of the subthreads in the same conversation.)
For me, the best part of having interesting conversations on HN is reading all the alternative points of view by smart people. Not much "productive" happens, from my point of view, by criticizing someone's show HN project, not much "productive" happens when you make blanket statements about what all people want. And not much "productive" happens by only agreeing with others.
So there might be another hidden motive behind what @kgwxd said. The comment he replied to literally insults the Poxi project, and perhaps @kgwxd was merely defending a Show HN project that's in a very early stage.
In my view, you may be defending the wrong person here. I want to see more show HN projects, and I want people to feel comfortable sharing their projects without fear of getting ripped to shreds, called a joke, and questioned why anyone would ever want to do such a thing. Let's be supportive.
So the point was to teach the commenter a lesson by responding unhelpfully?
>In my view, you may be defending the wrong person here.
So, because I was pointing out someone not responding constructively I am by necessity "defending" all points the other person makes? I think that is faulty reasoning.
