No, it's not functionality that sets Flickr apart: It's the photos themselves, and the Flickr community. Flickr puts the photos first, displaying them beautifully on the screen and giving details about how the photographer captured that shot. Because of its web counterpart, users can curate photos into albums that tell a story before sharing them via mobile. Photos captured with high-end DSLRs shine through Flickr, since users can zoom in and study a photo's detail. This is clearly an app for the art of photography.
