You should also keep in mind, that the german pirate party isn't only about copyright stuff.
They're also "the only" party in germany that represents the interests of web-centric citizens. While the conservative parties try to regulate the internet in germany more an more (you know, germany has A LOT of regulations, everywhere) the pirate party is a good alternative.
I'm really happy about this movement, even if they don't land a huge hit after a few years, you can see more younger people getting more interest in politics etc.
