This is actually a very smart initiative. There isn't much incentive, on the Hive network as a whole, to engage through comments as people usually have a very low default voting power for comments (like 5% or 10%).
But, as an author / content creator, receiving comments and engagement is what makes us happy 😅
That's the problem...If people are going to put the effort into commenting, we feel they should be acknowledged. And rewarded :)
