There are some coins trying to 'change the world' right now such as Auroracoin, Mazacoin... The concept of these coins is either taking banks (like the Iceland Central bank) or institutions (like the US Federal govt) head on... But Zeitcoin on the other hand, just seems like a fanclub for people that watched the movies. More than a superficial link to something such as the Venus Project would help as well.
As it is I don't see a reason to support this coin. And I have edited together a version of the Zeitgeist films (

You could say the same about nearly any crypto. Is litecoin changing the world? I don't see how, it's not even asic resistant anymore, yet it has the second highest market cap. You specifically mentioned Auroracoin, but many see that coin and it's 50% premine as a dubious proposition at best. The coins are going to be airdropped to the little people of Iceland? Really? Seems like it could do a great deal more harm than good if the original plan isn't seen through. Mazacoin is permanently inflationary and it's value is on a steady decline. Sure any of these could change the world, but it seems unlikely. I don't see that they have any greater chance to do so than Zeitcoin.
I can't speak for others, but I like Zeitcoin's specifications. I like the hybrid pow/pos distribution model and the potential energy savings they represent and yes I like the Zeitgeist inspired theme as well.
