This is really a monumental societal change.
3rd spaces are nearly completely destroyed, and online seems to be the main option for ppl now.
I met my partner at the dog park. I had just moved back to the city and she had just started taking her puppy to the park. My dog is 8 years older than her dog.
We didn't know until months later but she started going at the same time so she would see me and I was going at the same time so I would see her. We've been together for nearly 9 years.
Some third spaces are very specialized for certain activities but that is a bonus because something like a dog park means you already have common interest.
