In Pinterest, you make different boards, like “Décor” or “Food,” and then pin photos or quotes or recipes or whatever to the relevant boards. Pinterest remembers the last board you pinned to and sets that as the default board for the next pin. So, if you’re not paying attention, you could be sending out some very strange signals. It’s one thing when you accidentally pin double chocolate caramel cake onto “Health & Fitness”; it’s quite another when you pin a picture of a baby penguin onto “Yummy Foods.” And, I don’t know for sure, but I think that accidentally posting “Spicy Asian Meatballs” into “Sexy Men” may be enough to resurrect Freud. And with no easy way to switch large numbers of pins to other boards, you might just have to live with the implications.
