Proof of Stake seems to mean different things to different people. The early POS systems where flawed. In most of the discussions on POS I see people throwing out strawmen. Even worse, people won't give anything with a POS label the time of day, they have already written it off.
So when we say DPOS we automatically lose people. We need to get through people's knee jerk reactions.
So I am curious if there is another way to describe DPOS consensus without using POS.
Absolutely not. Stop competing for the same people over and over again. Bitcoin is one group of people, and there is a limited number of people who are interested in cryptocurrency enough to care about the technical specifics like Proof of Stake vs Proof of Work vs DPOS. Basically, the majority of people are never going to care.
And the people who are technically inclined will care, and must know the specs of Bitshares. Not everyone who is into technical details will be America, white, male, with a cypherpunk background. Not everyone will have had the chance to be an early miner (pre-ASIC). So for the most part DPOS can be marketed.
On the other hand once mining actually becomes decentralized again (and it will), and beneficial (folding proteins and searching for aliens), that is when Proof of Stake might be at a slight disadvantage, but again. Market MineBitshares to make Bitshares less susceptible. Don't stop marketing POS. That kind of flip flopping only shows weakness and insecurity.
