exciting mystery (the best kind)

So over the past week to 10 days, I've had 4 or 5 Etsy orders from customers in Brooklyn who sign up for Etsy the day they order. Hmmmm... is there a big happygirl ad on the subway I don't know about? Or is one of my previous Brooklyn customers doing a fantastic job of sharing the love? This is quite perplexing, but also pretty great!
