Good thinking. I guess the smart contract & transparency mechanism can be based solely on reputation and trust of community members first.

As for community coordination mechanism, Steempoll is already being made by @good-karma, but I think it could certainly be improved around the notion of community coordination / decision-making, and especially making it seem like a core utility that'll benefit users.

Thanks! I'll draw up something for this and source community members that are interested to get this rolling.
