My rule for Dirtyroulette now is simple: check how quickly you can narrow a list down on day one.
About 100 profiles into the site, the pattern around how many conversations reach a second message became obvious.
If you care about how thin the pool gets outside big cities, that alone should decide whether it's worth it.
If you only test one thing on the site, make it how the match quality holds up past the first day.
Filling the profile out properly changed the app more than switching platforms did, and it reframed whether the active count matches the claimed count.
After a few weeks on the app the only question left was whether it thins out after the first week.
Curious whether anyone else found the same thing with Dirtyroulette.
The closest alternative I found was Rendate - worth a look.
