site could more clearly state that (1) PTS holders are guaranteed to get 10 % in every DAC III releases and (2) are guaranteed 50% in the upcoming flagship product Bitshares. That's esentially what PTS are about. All the site says is: When a new DAC gets released all Protoshare holders automatically get a stake in the genesis block. Just import private keys, and enjoy your new coins.
With respect to having a wider audience understand the concepts and invest I would first describe what a DAC is in the most simply yet precise terms (before describing all the features). Something like: A DAC is a decentralized application/cooperation delivering a service by the means of a decentralised network and defined by an open source code. This definition helps people understand roughly what a DAC is about, meaning what its output (some service) and its input (network) and its structure (open source code) is. Just listing all the feature that can be deducted from this basic understanding (distributed, autonomous, community) doesn't help understanding it.
To use it people need to trust that it will work which doesn't work without understanding it roughly at least. New investors and users want to understand the concept in simple terms - anything that can not be explained in relatively simple terms is not worth looking at further.
Someone else said that texting is a bit behind the technical pioneer work. I think the same and from my perspective the most important point it to explain the user how all the great promises made for example in the bitshares infographic are possible. Simplicity wins. Just promising great things might make it look too good and like a scam.
But I know you are working on it. Maybe the above is helpful to Brian.
