It was lunchtime. I was checking my social media accounts, mindlessly munching on a piece of leftover pizza, when my Pinterest feed refreshed with two new pins from Megan Daniels, one of my friends from high school. She had added two photos of maternity outfits to a newly created board called “Future Daniels.” I messaged her. “I saw you had pinned maternity outfits [on Pinterest],” I wrote. “Are you pregnant?” “Yes I am,” she wrote back. “I’m due in August.” For those not familiar with Pinterest, it is a content-sharing tool that allows users to “pin” photos, videos, articles, graphics and other objects to their “pinboards.” Think of it as pinning a photo or a magazine column found online to a virtual bulletin board. Pinterest was called the fastest-growing social media network on the Internet last year.
