The limits are only where we draw the line or when we "think it can't be done", everything is possible, this is just one aspect of this social network that is yet to take off.
As the number of members/users grow so too shall the variety of posts and usage grow and expand into areas that include business 101 and who knows what all else.
Steemit offers boundless opportunities to all of us.
Just wait and see, it is only a matter of time!
