First of all, good to see you on here. Just saw your link on my YT video.
Secondly, I will slightly disagree. It's more about individual demand as most have in person. Facebook and Twitter trolls are usually rather weak people sitting in front of their keyboards that would never talk the way they do to people's faces. In fact they'd probably talk the way they do on Steemit.
I think if anything, Facebook and Twitter have changed the way people talk to each other and interact because they don't consider individual demand. They think they can hide and throw rocks at people.
The community on Steemit I've always found to be more realistic. People respect each other and if they disagree they make it known but they also don't start calling names. I think it's a good thing! :)
