I have a friend who is interested in using settlements of either real or phony money to offer incentives and change people's behavior in online settings and I'm going to talk with him about applying this to dating tonight.
Some of the reason why it is easy to meet people when you are in school is that you are not just doing it one on one but you are in a group of people that share activities and interests and couples can break off but they have the support of the group from before they meet all the way to the wedding and beyond.
A site that builds a real community could capture all of this. Another thing to think about is habit change. I've written about a recent experience I've had and I've been thinking about what I can do to right now to help it develop and I know I need to get practice in showing gratitude, giving complements and doing little nice things because I'd like to be able to show my love.
On today's online dating sites on the other hand you are feeling ugly or harried or angry or frustrated and none of those those feelings are going to help you give and receive love.
Another way to encourage this I think is making it a paid service. Filters out anyone just using it to look at pictures or waste time.
I liked the bumble founders idea of having LLMs trained on peoples texts/social-media activity and having them talk to each other and then matching people based on that. Might be a good way to determine that one daily match.
I think Hinge actually had a pretty good system when I was using it a few years ago. It had a strict bio format, which required every used to answer exactly 3 questions (of their choice) - this format allowed me to identify people who cared about genuinely meeting someone, and had the depth of character to communicate well with me. The incentive to over-share is gone, because you're limited to 3 answers. The incentive to under-share is gone, because you know everyone is also sharing so you're not going to look desperate. People who couldn't or wouldn't give 3 interesting and honest answers were easily ruled out and a lot of the alluring "mystery" of those under-filled profiles was stripped away.
