A long scientific list of what works and what doesn't in the online dating world. This reminds me that I really need a new BuzzFeed profile pic (the one I have now isn't even of me, it's a drawing of Claudia Kishi from the Babysitter's Club). So I'm going to go take a photo of myself doing something interesting outdoors and you should, too!
