It is good that the Economist mentioned Steemit. I would have thought by now Steem would have had a full article in the Economist. I'm sure it will happen soon enough.

90% of the Steem Power being held by 2% of the users sounds about right as well. It sounds bad but is not as much as a problem as many would think. The creation of the rewards pool will dilute that concentration of wealth. I also expect many of the whales to powerdown and leave once Steem reaches a target price. This would be quite gradual so as not to crash the price.
