You should try A/B testing your copy.

I don't understand the concept of openness and liberation as it applies to photos. To me, those are political concepts, not technological ones. Maybe I'm not in your target market, but to me it makes much more sense to tie "sync" and "share" to your copy more so than "open" and "liberation".

For example, if the name of your service was PhotoSync, and then if I went to the front page and saw a comparison between your service, Facebook, Flickr, and ICloud, I'd be very curious to see what you could offer over the options available to me.

Best to ride the coattails of those companies that have invested orders of magnitude more money to educate the market than to educate them yourselves.
