The demand for STEEM is still based mostly on expectation of future appreciation. This is at best high-risk venture capitalism. There is little demand for STEEM coming from selling products in exchange for STEEM. Steem Monsters cards come to mind first. Steemit Inc is generating some advertising revenue, which is very healthy and welcome and there are a few isolated examples of businesses setting up an account on Steem and powering up for the purpose of advertising their brand. One shining example of this is @coingecko that deserves all the love we can give it. Coingecko bought $18,000 worth of Steem in October and their goal is not to earn here but to make themselves known among Steemians. That's a wonderful example of the value proposition of Steem as outlined in the Steem whitepaper coming to life.
