Yes agree as @steevc says 5 years is a life time in the world of the internet but as Steemit continues to grow over that time we could have 100 or even 500 million authors But wouldn't it be better to have 10-50 million real contributors?
I see Steemit as a social blogging platform rather than a blockchain based superficial social network. It's a place of sharing knowledge and making connections . Yes I'd like to STEEM powering ecommerce and driving devices too.
