The notification is indeed a signal that provokes us to look further, curiosity with a little twinge often adorns, because of addiction? or maybe because of hope? it seems to be waiting for the curator to stop by and give a gift.

We have to admit that upvotes are the main attraction, here the role of comments is as a bridge to reach it, Engagement is an old word that has not been fully realized, so it is replaced with Learning, which I think even fades interaction. Although on the one hand I am also grateful that I don't see many fake comments in Steemit Challenges anymore.
