Maybe because we are seeing posts from other platforms as well. But, yes, I have noticed it too. There used to be some good replies. Nowadays, not a single one. And majority of people go for posting, without any positive interaction. The biggest reason behind it is: ecency.waves vote.
What can we do to make it better? I feel like Hive is full of people who love some capital attached, at least. So maybe, if consumers find out that there is some little bit of profit attached. They will do it as well.
