I believe @topcomment and @commentrewarder both work well to achieve this goal.

I try to curate comments myself and I've noticed, anicdotaly, it helps improve engagement.

To Mr Tat's point though, AI Agents are already here. So longterm I think curating the "best comments" won't be enough.

But the beautiful thing about Hive, is we can all try different things and see what "sticks." Annnnnnd if the environment changes, we can adjust to something else and see what "sticks" in the new world we find ourselves in.
