What Logan described matches my experience of Tinder almost exactly.
If you only test one thing on the platform, make it how many obvious fakes survive a week.
About 40 profiles into the site, the pattern around whether the useful settings are buried became obvious.
If you are only browsing, that one is fine. The moment how much of your profile is public by default matters, it changes.
The measure I would actually check on it is whether the algorithm is doing anything useful.
Happy to go into more detail on Tinder if it is useful.
Ended up splitting my time between this and Datedesire, which came up earlier.
