I dig it. It would be super cool to see the interface alter in some way to indicate time, maybe invert colors after a steemit "night" creeps in. On another note - having a universal time for steemit would actually be really logistically useful for things like competition entry deadlines, coordinating posts etc...
Thinking bout it, definitely a bad idea to decentralize activities around steemit, if decentralization is the first guiding principle..
