We've gone full circle and reinvented the dating agency. If technology fulfils its original promises we would ideally be in a world where people didn't have "too little free time to meet people" and relationships would happen organically again.
It strikes me that the problems are more related to increased isolation/individualism, increased distraction, degradation of real-world communities, and increased fear of making unwanted/unexpected advances. People who have free time just aren't choosing to use it in ways that encourage the creation of organic relationships.
