We can watch every time someone looks at a profile. Do they choose to send that person a message? We can look at every message that's sent, and we can determine, was that message replied to or not.

When people talk about the impact of mobile dating, everyone focuses on real-time meeting - this idea that my pocket will vibrate every time a hot girl walks by. That's important. But it's not transformative.

Your goal in an online dating profile and in your first message to somebody is to strike up a conversation.

We choose mania over boredom every time.

Because we're able to adjust for compatibility - and what that means is we've already normalized for how well we think each person is going to get along with the other person - the only factor left in determining response rate, really, is the aesthetic appearance of the person who sent you that message.

Asked to choose between money and fame, I'd choose the latter every time.
