Interesting to say the least but careful of anyone offering information that is already biased based on his impression of the developer of Steemit. There are some great points brought up but also an underlying tone of negativity towards Steem and it's future. Ultimately it is about trust in the same way FIAT currency is and if this user base has trust and people see value in it then it wont matter if the early adopters sell out as there will continue to be an influx of new creators and Steem users IMO.
