In a way, its kind of complicated. It has a lot of moving parts. There's actually 4 different kinds of currencies
(captive steem, free steem, vests, SBD) each of which can convert at various rates to at least 2 of the others, adn three of which can convert to the dollar.

But at the end of the day, i think its better to go with the difficult economic model that people will might find hard to entirely grasp than go with the the facile model that says "value whats value its all stone soup anyway"... I think there are a lot of good ideas in this tag, but im troubled that many of the posts (especially the ducktales one) will come off as scammy and hinder adoption....
