The average number of comments per post is going down, but the daily number of users that are posting is going up. Both on both of the blockchains.
Almost everyone is focusing on their own posts, and not on caring about and supporting each other. If the people would focus on supporting each other, these blockchains would be literally become life changer for the most people. The cryptocurrencies would worth much more.
But the majority of the users are selfish and greedy. The ROI (return on investment) is more important to them.
They turn these blockchains into investing based platforms, and not into social networks, where the people would team up with each other.
Imagine investing love, care and time, instead of money.
That way would be better for everyone.
