Discussion is much more focused here and not that much actually occurs. E.g. try following https://news.ycombinator.com/newcomments https://news.ycombinator.com/newcomments and most of the time it's not difficult to read through every single comment being made. If what you're looking for is well discussed on HN regularly though then it's great.
