In my social circles, at least, the answer is yes. I live in a major city with many people from diverse backgrounds. It might be different in areas where tech people make up the majority.

I know for a fact that I wouldn't have been invited to some parties or met some really fun people if I didn't have Instagram. You don't have to post or be very active; you just need to have an account.

No, this is not true.

News to me. But I just left my 20's so maybe I'm late off the boat.

I'm not installing anything Meta for any potential date. maybe Twitter but that's already pushing it.

Likewise, just left 20s. I'd be shocked if anyone I'm dating red flags me for not having social media . Well I do have Linkedin if that counts
