That sounds reasonable, but then you have the issue with filter bubbles on social media. On the other hand, if QP became viral, it would actually spread along social connections, so it should be able to completely ignore filter bubbles, so long as they are not inherently social in nature (meaning, it would be cultural bubbles that prevent further propagation, not technology-induced bubbles).
Perhaps that’s because social media consists of mostly spam almost by definition? 
Yeah, I guess it would work best, if that was a blog post on a really popular blog. Those get a lot of attention anyway, so the chance the become viral increases.
Yeah, I guess you are right. Though it’s hard to compress the most important information about an innovative system like QP into 10 minutes or less.
That sounds very challenging, because new ideas aren’t easily understood by most people.
Anyway, if there’s anything that could spread virally about QP it’s that if it was adopted successfully and widely then you would get all kinds of open source digital goods for free (see Digital Abundance)! Consumers are the largest target audience, and they are the ones that can make QP viral. If we could emulate the early success of the Pirate Parties, that would be huge! There are of course other angles and advantages to QP, but I guess they are harder to explain and to sell, and have smaller target audiences.
