Man, that's so cool. Old-time, person-to-person promotion. That's a great example. I know how hard it may be to approach perfect strangers and persuade them to not see you as a threat.
I recently conducted a survey about people's view on the military and it was tough, especialy becasue of the subject matter. But this is different and i'm sure people, especially tech-savy people, will embrace Dtube as the next media revolution.
