This is cool, I remember either OkCupid of Plenty of Fish, used to be a really interesting exercise in self reflection.

You could only see someone else's answer to a question if you answered it.

The questions would sometimes get deeply personal.

It would make me self-reflect a lot on what an honest answer was, and whether I wanted other people to see my answer.

And if not, why? Was there something I was embarrassed about? Should I be? If so, should I fix that thing?

I didn't really care about the dating aspect as much as the exercise in critical self evaluation.
