Maybe I am opening already open doors, but as a newbie I see one crucial development. Getting through the door. Being an older person trying to get into this there should be more hard work getting the information out about safe and tried traders, like paypal or the likes. Names people have heard before, I mean, most people won't trust zipzap that comes out of nowhere. The larger group are just like me. We got some cash and are interested, but there are many roadblocks until getting in. Maybe put more effort in step-by-step descriptions, keeping them updated. And, I'm not lazy, I search the web, what I talk about is knowing how to build a trustworthy way to participate in this experiment (as I see it).
Great comment, when you look round you will see, members have tried to take a technical subject and make it accesable. Obviously some things are in development, you can help with any level of expertise and your opinion as a new user is usefull.
