I think casual, more informal dates have been very common for a long time in queer cultures. Asking for somebody out for coffee is "safer" in a world where safety still matters. So the coffee date has gained social momentum, I think, even in situations where safety is not a motivating factor.

Should queer couples date more formally, though? I don't know. Is it necessary to invest money and creativity to get to know somebody? I can see arguments both ways, and I can say I've occasionally enjoyed being wined and dined, as well as playing wine-and-dine host. But the strongest relationships of my life did not start out with series of formal dates. So ... take that for whatever it's worth.
