I too agree with this "Everything is not about money." Hive is a great platform indeed, I am also enjoying here and more importantly, scrolling on other social sites feels like a waste of time but being active here feels like I am doing something productive. Also, you are right The rewards should be considered as a bonus. Instead of wasting time on other social sites for nothing, it is better to spend some time here reading good content, connecting with good people, and enjoying some rewards.
Btw this microblogging is really a nice idea!
