This is a social platform, I think in this blockchain everyone knows what social platform is, although I am not using Facebook for a long time but I like to point out something. On Facebook if we post something that is for fun, when someone comments in our post, we do reply. Sometimes people do post some awesome work we do appreciate them with a valuable comment, but for all of this Facebook doesn't give us a penny. But here you are rewarded for that, if someone not does this then he is not in the right path, that's simple.
