Ask HN: Why does Facebook suck for making new friends?

Making new friends outside of school or work is difficult. Part of Facebook's mission is to "stay connected with friends" yet they're not leveraging their ubiquitous platform to make it easy for people in close proximity with similar interests to find each other. In my experience, what usually happens is you start off with a core group of "friends" from school (really acquaintances), add a few more so-called "friends" as time goes on, and you ultimately end up in a bubble with people you barely share anything in common with. The only alternative is to seek out "groups" of one kind or another but there's a lot more friction and effort required in that process. I'm sure if Facebook wanted to do this, they would have already. So what's stopping them? Why is Facebook the perfect platform for everyone's wackaloon uncle to share Breitbart articles on and not the spot to find someone to play Settlers of Catan with?
