I came from days of dialup and gone through yahoo groups, Myspace, tons of geocity sites, ask jeevs, LiveJournal, and so on. Sites will only be an attraction tell something comes that offers more. With federation and decentralized systems coming up, the hold on people and corporations trying to use you as a commodity will only tarnish the shine that it once was. When companies hold a noose around your neck thinking there isn't another option, telling you to go ahaid and jump, thinking no one will and when something comes by that makes the jump just a step down and you can take off the noose, there is nothing that they can hold onto anymore. They cannot say you have nowhere else to go. With the choice around in a federated system, you cannot be held hostage by a single entity. When people have the freedom of choice, the people win.
