i could list a lot, but ultimately what it comes down to is to ask
what is the point of a blogging website where all you do is blog and give each other thumbs up or thumbs down?
Sort of a trick question, but the answer is that its functionally useless for the grandier scheme of things. Theres a billion more uses for the blockchain, but the first step is to create value beyond content.
There needs to be more reasons to exchange steem and SBD, to create an economy not just focused on externalizing the rewards (cashing out). If there is an economic incentive to keep the money inside for commerce or other reasons, then people are much more likely to see some functional use, other than talking shit and paying themselves to do it.
