I want to update my statement:
Humans will come and stay, if humans invite them.
If this is to be a social platform, there has to be more human interaction not less.
Looking back at the short history of Steem, i saw people come for the tokens, set up voting and comment bots and left to be social on Fakebook.
Does not have to be a bad thing, if you only can post once a day as a new user, many forums have such restrictions to avoid spam and build sustainable communities.
If other real users on Steem want new users to be more active they will delegate SP and create even more social value.
I will comment on the second part later, have to run to rescue more food waste. Peace.
