Let’s not clone trash. Tinder sucks because it has no matching mechanism to filter out incompatible people. To find one interesting profile on Tinder I have to swipe about 500 profiles. To get more matches, I risk some false positives and like ~2% of profiles. Then I need to filter the matches in person. Very inefficient, a waste of time.

The opposite of that was OkCupid before Match Group destroyed it.

Not all places went eternal September:
Some sites/apps had filters to hide low effort people.
Some had strict rules that were enforced, so even if you were clueless coming in, you would upskill fast while using it.
Some had a good onboarding course making upskilling a breeze.
