Unless someone has found an additional 24 hours in the day, I don't know how they can be on two Steemits - the real one and the clone.

When you post and comment and share and power-up here, you increase the value of the blockchain. If you do it somewhere else, it's probably a loss for Steemit and a gain for the other place. Everyone can do whatever they want, and so can I. I will be going through my Witness votes very carefully over the next few days.
