The site is a simple and fun way to see what other people are doing en masse. For example, as I write this, 23 people are tired of the rain, five people are sneezing, and two are in the club. The site is meant for sheer entertainment value, and if you see something on the list that you're currently doing, help add it to the trending topics by clicking "me too!" The site is integrated with your Twitter account, so you can broadcast your identity or leave it anonymous . . . which will come in handy if you want to tell the world that you're not wearing any underwear (five people are currently doing that).
