I think SMT's have amazing potential for artists and content creators to form communities that target readers and potential clients. Whether you are an amateur or a professional. The communities themselves will have more control over content, membership and rewards.

And.. I didn't put in my original thought...

This would allow communities to define their own payouts. With a better UI and the ability to control certain aspects such as membership to keep out the spam & scammers I see no reason content couldn't receive rewards years later.

Something that would be a nightmare here on steemit.com.
