I bet they're technically capable of duplicating, maybe even by you on your own, same goes for Snapchat. Yet they don't, because just like a lot of the social apps that are succesful, it's not the technical innovation that makes it valuable, but the network of people that support it, and I think just as important, eventually being able to monetize it (Remember Vine?)
Also the already stored data makes it quite the treasure. Even if every user instantly stops using it, it'll still be very valuable due to the existing data (if they keep it).
Too stray off-topic though somewhat on a self-created tangent: There's an app called Flitsmeister in the Metherlands (and abroad but several countries banned it) that keeps on growing. I wonder when they will be bought out. Not necessarily for the active social network behind it, but rather for the data that is already there. I believe such a vast amount of historic data is hugely valuable on it's own. I wonder by who, when and for how much they will be bought out.
