Using social media shapes who we are, and how we see ourselves. Social media relies on identity: on handles or names or pseudonyms that represent us and our contributions to the rest of our networks. Pinterest is the same: when I sign up, I get an account, under a name of my choosing. People can see what I share. Being “re-pinned” means what I’m sharing is stuff people want to see. To our networks, we are what we share. ... Curation is as much a part of our digital identity practices as creation, today. It’s what Pinterest operates on, entirely. But at the express expense of creation.
