The difference is that everyone around you contribute to the "events" that is happening around you, not just your followers. They have an algorithm to recognize from the pictures what is going on around you. That's the problem they claim to solved.
i'll just keep playing devils advocate lol...i think there is a limit to how many "social networks" that a person is willing to use...also this feature could be incorporated into Facebook or twitter, no?
I don't think there is a limit to any network or business. Someone will always find a way to do things that the existing do not do, or don't do well.
Sure, it could be incorporates into FB or twitter, but that will be a big shift in their business. Are they willing to do that?
Things are going more visual and I believe that's what Color.com is betting on. Visual search.
