Thank you, ladies and gentlemen and those of you still making up your minds. Welcome to the OkCupid refresher course.

It’s great to see so many of you here. And to the fellow in the back with the blowup doll, please deflate her. Yes, I know she makes you feel more confident, but hopefully, when this class is over, you won’t need her anymore. Oh, I see, she’s your sister. Then welcome to class, sister. There’s someone for everyone in online dating land.

Let’s get started. First, your profile photo. This is the most important element in online dating, which determines whether users will want to meet you and you’ll be off on the most intoxicating dates you can imagine — Rome, Paris, London — or whether you will die alone.

There are three things to remember for your photo: smile, smile and smile. No one wants to see a potential mate scowling and looking menacing. That comes later. And, of course, photos should have been taken within the last two years, which is 10 years in online dating time.
