It's hard for me to even imagine "coder" as a dating persona; why would anyone care? Income bracket, maybe, but there are already matchmaking services/filters for that. Passion for technology? Maybe, but there are already communities for that where you can meet others without the overbearing expectation of romance.
In general I think dating and social loneliness is already heavily lopsided against hetero men; women don't need a "find me a dev who wants to date me" app, their existence is constantly bombarded with that. Why would they ever sign up for something like this?
I don't know how this would play out for queer devs, so I won't speculate there.
