Does Colour need a certain critical mass to even start to be useful? I tried it in Sydney, at some very busy places around the CBD and I only ever saw one other photo from someone else.
Of course, I could have been using the tool wrong because I really had no idea which symbol did what, but seeing that one other pic suggested to me it was working and getting nearby photos.
I guess a different question is, can you define "useful"?
Outside of maybe seeing immediate photos from people closer to the front row at a concert, I can't think of a use for color. But I could just be unimaginative about this kind of thing.
