It should be about real, actual, genuine interest about content in general.
Like on properly working social networks.
As I currently see it on Hive, it is mostly about Hive Power.
Some Hive accounts have high amounts of Hive Power, and they always receive comments.

I know. Honestly is not really much a popular thing nowadays.
Many people do not even like it.
But it is still one of the most valuable features of being human.
