Attention/contribution token 

Key features
* initial (uniform) currency distribution among network participants
* funds can be invested (Steem Power) or lent (Steem Dollars)
* participants vote on contributions of each other, and network calculates financial rewards; *work* is rewarded
	* voting can be positive or negative
    	* negative is in part intended to dissuade high-value participants from voting for themselves
    * there is a limit on the voting rate

* build on Graphene -- scales well, can support Reddit volume
