Sure, a place that continues to adapt and engage with in a rapidly changing world (not just tech, but in general) is a great thing, and difficult to do depending on the userbase. For a general forum (i.e. not split into specific subreddits), HN does a really good job of providing both "classic" and new/current discussion topics. I never doubt that there won't be at least one or two every interesting things on the front page on any day, and that's an obvious incentive to (habitually) visit and participate in discussions.

As for HN's civility, relative to many other places (twitter, reddit, news sites comment sections), I think that's a credit to the moderation policy and not something that would happen on its own. I see the effort in moderation as being cause+correlation of the community civility. And if civility were to noticeably decline, I'd take that as a sign that YC was less invested in maintaining and growing HN as a community and discussion forum.
