You know..... ProtoShares are really difficult to explain without sounding like a scam. I recommend we focus on the up coming BitShare ecosystem as a whole. Then, we can talk about the soon to be released Keyhotee, urging people to get into Keyhotee early to secure a great name for the future. And, oh by the way, BitShares aren't out yet and can't be bought or mined. But! You can buy/mine protoShares to help support the current phase of development. Also, in reward to early adopters and help for growing the BitShares project, each ProtoShare will give you an equal Share of each future DAC released. And then you can have a simple explanation of how this works. I'm afraid we really need to look at Mastercoin for a roadmap here. Mastercoin looks much bigger than they actually are. The have like 10 sites with FAQs and explanations of the project. But they are actually a ways off from being ready. They've done a great job of explaining how early adopters will benefit if the project takes off. I think we should do the same. Show people the vision of the project and then tell them how they can get involved.
