Good point. Those are some expensive mugs!!

For how much users should pay - it's quite interesting. The money that steemit pays its users is entirely democratic. It issues roughly the same amount of currency daily, and distributes this to writers based on up-votes.

Funny enough, the more advertising dollars enter the ecosystem, and the more the world values the STEEM cryptocurrency, the more valuable the payments will be.

Watch out for even higher payments in the future, when Smart Media Tokens increase the demand for STEEM. Another way of looking at it is, if facebook distributed its massive profits to to users who got the most likes... how much would they be earning daily for 'silly' posts? Hundreds? Thousands? More?

Their posts are what is making facebook to be a profitable company.
