I don't know. I think some things are important. Someone who loves live music and goes to see something a few nights a week would probably be happier with someone else who, all other things equal, had a similar interest. If you're looking to pair people up in ways that won't work long term, because you're a company of ghouls looking to make money, then matching the music lover with the music disliker is better for your business. With enough data points, you can probably make some confident predictions.

Hinge also isn't making you pick from dichotomies. You enter free text for most of it, and pick as many from a list as you like for others.

This was Hinge, which is owned by Match Group (who own okcupid and many others). It's the least bad, I found, but that is extremely faint praise.

I used to use OKCupid way back. It used to be better. I'm pretty sure you could search. Like you could just type in "Star Trek" or "Dark Souls" and find people who had that on their profile. Nowadays you just take what the algorithm gives you.

briefly experimented with an open relationship.

Was it a mutual idea or did one of you suggest it? What were the reasons for stopping it?

That's nice to hear, thank you. I got married right before Tinder and was jealous of how much easier it seemed. Now reading these comments/article, the easy was the problem.
