The good ol' wait and see approach, eh? :D
Maybe, but I can't clearly see why scaling would help with this issue. For my own part I believe most issues seen early tend to persist, even if one tries to ignore them. It is also usually easier to change things up in the beginning than after everyone has gotten comfortable with the way things are.
Your arguments are valid, but the thing is, I just don't think steemit is large enough yet to make the assumption we're not commenting enough. I think relatively we are, but there's just too little of us.
How many steemers are there?
I don't know, I'd like to know!
