I consider this with a lot of "solutions" that aren't doing a great job, and I'm not sure. Think it's human nature to want more and for things to be better. I've made great friends online and they're the main reason I've been able to keep a grounded look at the world. I definitely should go touch grass though.
I hold quite negative views of social media personally. I don't see how it could be built in a way that could suitably replace in-person socialisation. Perhaps the best idea would be a meet-up arranging app, but then that could be handled in a simple chat application really.
