the cost of servers/data storage were probably more (a lot more) than the 70k steem they made curating/posting. That means they have been operating at a loss with a pretty revolutionary platform.
With their own blockchain (centered around content) and own coin distribution they will make more money and so will the content creators. And they might be able to compete with the likes of twitch/youtube.
Steem is not centered around content. Steem is centered around power.
They are not revolutionary, a streaming service that requires you to download real streaming software really revolutionary????
Their own blockchain? Look closer, you sure its not a web page?
