Interesting stats on the infographics you posted, especially about how we do not usually share the information that we are most passionate about.
From my short experience on Steemit, I have seen otherwise, even though there is a lot of pointless posts being created. However, I have been selective about who I follow and have tried to give meaningful commentary on people's posts. That seems to be a challenge these days for many people it seems.
The one thing I have seen on Steemit, that a large percentage of the posts are quite positive. I am not sure if this is because the authors are garnering upvotes and have reserved their true opinions foe the sake of acceptance on the platform mearly to earn.
I am sure as the platform matures, the quantity of meaningful conversations will increase.
Cheers.
