A ponzi is where people take THEIR OWN MONEY and give it to other people. Steemit allows you to participate in allocating the minting of a cryptocurrency in a weighted vote style. Semi-democratic or democratic whatever you want to call Steemit it is not a ponzi, calling Steemit a ponzi in 2016 will be like calling Bitcoin magic internet money in 2009
