Would You Use a Dating App That Matches Based on Your YouTube History?


've been thinking about a different approach to online dating—what if instead of swiping based on looks or filling out long personality tests, you were matched based on your YouTube watch history and recommendations?

The idea is to use real behavioral data (what you actually watch) to match people with shared interests. Instead of awkward small talk, the app would also suggest conversation starters based on mutual content (e.g., "You both watch a lot of Veritasium—what's your favorite experiment?").

A few questions for the HN community:

Would you trust an app like this with your YouTube history (or would manual topic selection work better)? Do you think real behavioral data is better than self-reported interests for dating? What are the biggest flaws in this approach that I might be missing? Right now, I’m considering an MVP where users upload their YouTube history manually (Google Takeout) or connect their account via OAuth. Curious to hear your thoughts—does this sound like something that solves a real problem in dating apps?

Don't make another trendy AI-based dating service, people are sick of those. They only use them because they are forced to do so. First, figure out how to create a safe dating web site, ensure personal data security and don't collect anything you don't absolutely need, don't use too much telemetry and don't keep it for too long and especially don't use location-based telemetry, eliminate the bot problem which is inevitable, eliminate the problem of child predators which is inevitable, and things like that. The goal is to ensure that you only hold the data you require, and avoid any further data, since in a security breach user data is radioactive. Once you know how to do those things, just make a site where people can post a deep profile and search based on those profiles and perhaps have some sort of questions that help match people on a basic level with hobbies, values, etc. People will figure out how to find folks they might like to date and will take it from there. If you used Match back in ~2008 or so when it was profiles and dating questions, that's the goal. I met my wife there, and it was an alright experience. From stories I hear today, I would probably never date again!

I wouldn't be into something like this. I don't think my YouTube history gives a reasonable insight into who I am or who would be a good match for me. Even if it did, I don't think that automated analysis of that history can be done with reasonable accuracy (I'm basing that on how awful YouTube recommendations are).

How does this determine signal wrt shared core values (honesty, trust, respect, open communication, compassion, authenticity, equality)? Interests ebb and flow over a lifetime, who you are as a person is more material to a successful, lasting partnership.

Many shared interests are not necessarily a good proxy for spousal or romantic compatibility.

try the (or some) watch later playlist, with all the stuff a person would do or wants to do 'if' they had [time, xyz] ...

no better way to start doing and getting to know people.

a picture, quick info from what height one jumps from, and an attempt to pack the brutality of one's entire personality into one paragraph.
