The potential customer base for Pinterest is half of humanity–i.e., all women. Because most of us are bottomless pits of wanting and Pinterest gives us a way to catalogue the myriad things we want. It’s been hypothesized that men don’t use Pinterest because they’re ‘not into scrapbooking’ or they’re ‘too foggybrained’ to remember to pin items they like. But I think these hypotheses are wrong. Men don’t use Pinterest because they only really want 3 things, which don’t need cataloging: food, sex, and TV/the Internet.
