There is confusion here because usually shares are issued in a "company" or "corporation" which is separate from the individual.
Look at it this way: The company, SatoshiDice, issued the shares. They then gave them all to evoorhees as compensation for building the company. He is now free to sell as many of them as he wants, and keep the ones which don't sell.
Sure. I dont have an issue with this.
Im staying away from S.DICE simply because of the risk of MPEX and the behaviour of their PR account.
