is an online dating site that, rather than relying on the data produced by a complex algorithm of self-reported answers, uses a person's own public Facebook profile.

To be clear:

Nobody on Facebook can see you're using, but integrating with Facebook allows us to ensure we show real people with real friends and interests, and it allows us to dramatically simplify the process of online dating - signing up takes two minutes. We also filter out your Facebook friends so you don't see people you know.

As dating site do, generates a lot of data. Last month, it generated over 100,000 yes/no answers. "[P]eople say yes when they're interested in someone, and no if they're not. So, for each person, you have something we call the 'Desirability Quotient' — the percentage of "yes" answers out of the total yes and nos that person receives." There is also the "Selectivity Quotient" — the percentage of yes answers that person gives to other people.


The people behind are interested in finding out whether any of that data can be used to the benefit of user experience, so they've started a series of blog posts within which they analyze and present their findings on a given set of collected data.

The first set of data they looked at and blogged about was email domains. On the outset, expected to find that Gmail users were more attractive than users of other email domains.


To begin, it is established that has a strong Gmail skew, which the say is to be expected because their core user is a "young, college-educated, tech-savvy person in the Bay Area," and this person "usually uses Gmail."

The chart shows the percentage of yes's for each domain (the Desirability Quotient) in aggregate. Analyzing the data reveals that, on average, about a third of people browsing a profile say "yes." Of the major email domains, Gmail does seem to be the most "desirable," followed by Hotmail and then Yahoo. "Other" does quite well, too, and that will come up later on.

This is the same chart as above, but broken down by gender. On, which skews younger, women get a lot more yes clicks than men do. The least desirable group is Yahoo men, getting a full 5% fewer yes clicks than Gmail men do. And Yahoo women fare better than women using Hotmail.

Interestingly, women using "other" email domains get almost a full 10% more "yes" clicks than average. Mostly, these are .edus, college email accounts, for women who are either in college or recent graduates who haven't updated the email they use for their Facebook accounts. It's not especially surprising or new information, but only further supports the theory that a young, college educated woman is the most desirable to date.


• users can't see each others' email addresses—only we can see this information in our database.
• has an option for non-binary genders, but we don't have enough data on these users to include them in this analysis. We also didn't have enough data to include AOL users.
• This is basic analysis, and not perfect. Ideally this data would be adjusted for age and other factors – eg, certain email domains skew younger and this may be a confounding factor.
