I think that at the moment, there is a knowledge treshold preventing people from starting on steemit or dtube. Just signing in and getting your password on steemit can be problematic. If people manage to get over this, then they will be faced with the problematic of steem, sbd, steem power, voting power...
So I think that in order to bring people to steemit, there is a real need to provide in depth tutorials and show them the benefits of it.
