it's always been the pattern for social networks. For individual social networks, yes. But what if we lumped all social networks together, and looked at aggregate usage over time? It would constantly increase. I think that instead of dying out, it will plateau until we reach saturation. Other communication technologies follow this model: radio, television, telephones, cell phones, etc. Rather than being a novelty, I think that the past decade has demonstrated that online social networks are something most people want and will continue to use. To be clear, you and I are making contradicting factual predictions about the future. Neither of us knows which prediction will turn out to be true. At the moment, the available data fits both of our predictions. We'll know in about 20 years.
