A) don't want to be everybody's fb friends/g+/etc who were in a friend's birthday party, but still wants to share the photos she took at the party
B) easy for anybody to share an album and other to participate - usually after such a birthday as mentioned above, one person's photos are in fb, other one's in G+, third's in dropbox... in other words, people who wants to share together.
So basically everyone who has a need to share photos but they don't have a common service to do so.
Hi, sounds nice.
Have you checked projects that are working on this such as:
Cluster, BirdBox, Photo Circle, Adobe - GroupPix, SeaHorse, EverSnap, CapsuleCam.
How do you differentiate your product from those services?
