well, you are right :). Hashnode cannot compete with stackoverflow in that matter. I think everyone who is using this plattform for a while knows that.
But .... you get more friendly answers here, people don't delete your question, you don't get downvoted just because people don't agree with you.
it's a conversational community. That's the whole point, meanwhile in stackoverflow people do discuss as well but it's not the main focus, the focus is sharing solutions for specific problem cases. And other people decide the value of your question in relation to their solution pool.
So hashnode is somewhere between hackernew, quora, redit and stack-overflow it depends what you want in the end.
We will try to answer all questions to the best of our knowledge if you prefer stack-overflow ... go for it.
