I disagree that the question (and thus, the discussion) are pointless though. I find both participating in and reading through these discussions valuable, as they make me analyze my viewpoints, as well as introducing me to opposing viewpoints I hadn't necessarily considered. For example, the poster who felt "an artist has the right to choose how their work is used" in this thread made me consider how I felt about that. I don't think I'd like my work to be turned into something I hate, but I'm not sure if that means I have a moral right to stop it.
Obviously, this discussion comes down to personal opinion on an artist's rights, but I can't say I've really closely examined what I think. We may not all agree, but some of us can come to a better understanding.
I don't have a solution, by the way.
Anyone can make an observation that things are broken (though perhaps not state it as succinctly), but coming up with a solution is both more interesting and challenging. If HN never moved into that stage, every story could be summed up in one or two comments, and it would basically just be a link aggregater.
