If I could make one suggestion, please make it more clear what your website and service does. The front page mentions that I have total "photo liberation" but that's just sort of buzz. I clicked on "overview" (not sure how many people would make it that far) and the headline is "Like WordPress for Photos" but if I wasn't tech savvy, I would have no idea what WordPress does. I spent about 2 minutes on the website (much longer than any consumer) and I still didn't quite get it.
Also, on the see the difference page it might help to compare yourself to Flickr and other photo services.
I don't mean any disrespect or offense, I just don't think your website is immediately clear.
Thanks for the suggestions. We haven't had any "non tech" folks look at the site yet but will definitely address anything that's not clear.
I expect most non-technical users to go to the hosted version which won't have nearly as much information but a straightforward way to get started. The project site is geared more for early adopters who care about said liberation, developers and theme makers.
The hosted version (currently designed by myself who has no creative juice) is at http://openphoto.me
As someone who loves photography, I'm deeply passionate about copyright remaining with the original artist. I guess I'm your target user.
The main thing that hit me about your current landing page is it's lack of vibrancy!
The photo apps/sites that do well (500px, Instagram) thrust beautiful images at you at every opportunity and it works!
While you aren't responsible for the quality of art stored in your accounts you are still trying to appeal to those that are attracted by great images and proving that others entrust their greatest works into this service.
Having some great photographers use your service that you could showcase,would speak volumes to other potential customers.
