This doesn't do much for anyone who doesn't know what the hell this is about. I recognize napster and piratebay, but have no idea what they have to do with a youtube link and whatever other links you have there.
Why would you not just link to the Piracy Megawiki if you're trying to get new people into piracy?
Edit: apologies, I didn't clock the community at first. It's still not straightforward about what this is about at all. And I don't think anyone is going to recognize the rentry logo.
Why would you design a poster to need to be flipped over too? Makes it harder to scan the QR code.
