You would need a large group of different skilled people to be able to do it successfully in a way that good points about the stories arise in the show, given the broad range of different kinds of topics that get submitted to HN.

But for that you already have the comments on HN, so it would have to add something more.

Maybe teaching something, or adding new comments from people that did not comment the story but are able to make some good points...

It would be nice if well thought...
