@charles1 I think the most important statement in your post was regarding the beta status of Steem. To date, Steem is, indeed, still in its infancy. It's existence is promulgated solely through word of mouth which brings roughly 2000 people per day to the platform.
Imagine, indeed, once real advertising begins? I would expect that a dramatic increase in membership will ensue following any sort of intentional, commercial promotion of the site. Once that happens, real wealth creation, monetary and creativity, will likely occur like has not yet been seen.
Good point, I agree with you...thanks for your comment
