"In [Tricia] Wang’s theory, a network like Facebook, which enforces real name registration and consists of a person’s friends and family from time immemorial, encourages bounded use. It’s like the small town you never left, the grammar school class you couldn’t pass out of, the first dead-end job. It’s a network mired in past and present, and by its nature it enforces a limited sense of identity and expression.

By contrast, something like Tumblr encourages unbounded use. It allows you to experiment and play. It’s the big city, and each new tumblelog you create is like a new bar or neighborhood where you can try on a new self and see how it fits. In one instant you can be a pug lover, reblogging the best animated GIFs of the flat-faced dogs. In the next, you can dive deep into the Go Pro snowboarding community and post snaps from your latest run.

Hence Wang’s notion of the elastic self. Like rubber bands, when we step into Tumblr we can stretch and reshape ourselves into different configurations. Each new hat we try on stretches the rubber band just a little bit further, and over time it might evolve into a new configuration. This allows for remarkable opportunities to explore different potentials of self and self-expression."

"What mainly goes up… is not the core network but the number of casual contacts that people track more passively"

"People often wander around cemeteries and look at gravestones and wonder who that person was. By using the QR codes they can find out all they need to know"
