Crowdsourcing will be the core means of marketing Steem going forward.
I say STEEM instead of Steemit, because the two go hand in hand... but in the event we create value on another app using Steem, the benefits will flow to Steemit as well.
Steemit Inc is here to make the Steem blockchain a success. Steemit.com just happens to be our first use case, and hopefully the first major success on Steem.
