Sometimes, I think we have failed as a social network... Especially when we have to write/talk/explain to people how to "act" on a social network... Everything you said is correct, but the fact that we have to SAY that is disappointing...
It should be a normal thing that, on a social network, you create content, comment, have a discussion, appreciate others, and respect each other...
Hopefully, one day, we will get there...
