If you don't dabble in Pinterest, consider yourself blissfully ignorant. But, let's say you're going to a party and need ideas on how to jazz up your eggnog. Pinterest probably has lots of suggestions. See, you get "boards" that are based on topics and you "pin" things you like to those boards. Then, people can follow your boards and vice versa. I think. Or, you can just look at stuff. Forever.
The boards and pins come at you fast. As you peruse the site, that draft you just felt is underachievement wafting in the room. The warm cloak of self-confidence you worked hard to harness over your strong shoulders gets yanked off. Awash in a time portal, hours are wasted while you chase rabbits in a fog. You'll spend the rest of the day trying to figure out why you don't eat more quinoa, where burlap crafts have been all your life and contemplate how to dig up a grand for a new camera that will properly capture the essence of sea salt, rather, fluer de sel de Camargue, atop your adorable caramel shortbread cookies.
