I've stated this before, but it bears repeating:
Google does not make money from you finding what you're looking for.
Google only makes money from you hunting for what you're looking for.
Repeating problematic incentives is fine. Ignoring counteracting incentives is misleading but popular in all debates.
- Monthly: Incentives variable, but generally low quality results (for slot machine psychology.)
- For each match/hookup/"real" relationship: Incentives results that produce relationships that last exactly long enough to be considered a match/hookup/"real" relationship.
- One-time upfront: Incentivize finding the best available candidate ASAP in order to save server costs.
- Monthly, cost propositional to success rate: Optimizing for some specific length of relationship that someone calculated to be optimal.
There are most likely other funding possibilities, and I've most likely misunderstood some rule of economics. Note that none of these optimize specifically for happiness in relationships, only for longevity.
