I used to think they would follow the xanga / myspace train and be blown out of the water by something but that's not the case anymore. They have proven they can just buy any competitors or quickly copy their features, and "all my friends are on fb/insta/whatsapp" will keep the vast majority of the users entwined in one way or another. Regardless of usage metrics, if you only use their apps for social, that's a win in itself.
