Maybe I'll to try implement one of my ideas for Tinder. That is A/B testing of profiles in different locations. Let's say I live in SF and could set up a weeks worth of testing with various different profile pictures and determine which one gets the most swipe rights in different parts of the country. Then I could use that profile in my own location.
Sounds like a good idea for a service, figure out the optimal profiles for people with different combinations of pictures/text, and return the results. Tinder consulting.
