X user Nicole Ruiz shares this photo from the recent New York City Marathon. I'm 99% certain that I have identified the woman and found her on Instagram, but will refrain from naming her as she may prefer to remain private.
Anyway, the lady is an innovator. She wants a boyfriend and offers a QR code that links to her Instagram page. This is the kind of out-of-the-box thinking that helps break out of the glutted dating market. She's direct about what she wants and markets herself in a novel and attention-getting fashion. If I were single, I might try this at an anime fandom convention (although with perhaps different results).
