Well, you have this public record of who's dated who and potentially who has fucked who.
It would be interesting for a Tinder-esque model to allow you to see who each person matches, to get a better idea of what the person is looking for.
Plus, it'd make quite the interesting statistics for dating dynamics between men and women, as the data is public and auditable. Can't be tampered with or removed.
For sure, then comes the issue of privacy. You need a way to selectively reveal information.
