This leads to difficulties running a dating site because women will only say yes to 9/10 or better men, but men will message anyone with a pulse which in turn inflates female expectations.
Many women only ever join dating sites as an ego boost, with no intention to actually go on dates.
I had the idea that the way this could work is a totally automated match making system akin to Uber where you are penalised for not accepting matches made by the system. You don’t have to get married or anything, but if you don’t both turn up at the same GPS time space coordinates it counts against you.
Similarly, the system should require an up front ~$50 fee from both sexes per date. You don’t get it back if you stand up a date.
Etc…
It would be very hard to bootstrap, but once going it would produce many more long term partnerships than “swipe right” style apps.
