That is great news, I hope they will accept US customers soon. Good idea with @steem.marketing.
May I suggest creating a @steem.ads account or something like that and initiating some sort of engagement with ads Steemit displaying now and will display in the future? This way Steemit or companies may be able to directly reward those who consume their ads, engage with companies, provide feedback, and buy their products/services.
I think Steemit is in a unique position to reinvent how ads are done online. This in return may increase the interest of companies to create accounts here and interact with their customers directly.
