Holy crap, I didn’t realize that site still existed. I’ve since lost touch, but I actually met some cool people from around the world that I was friends with for years through that site when I was a teenager 20 years ago.

I think that’s a part of it. They’re also usually the ones who are likely to end up being longer-term residents so they’re more invested.

I don’t mind chatting, but usually when a I’m outside my apartment I’m in the process of doing something. Personally I hate getting trapped in small talk when I’m just trying to spend 60 seconds to take my trash out or walk to my car.

Nope. Neighbors in apartments change far too frequently for various reasons - life changes, rent hikes, property issues, etc. It very rarely seems worth the time to invest in a potential acquaintanceship. The only people that ever seem to be eager to be friends in my experiences end up being the elderly and the younger folks anyway.

It also makes it far more awkward when you have to eventually have a neighborly conversation and ask them to not leave their trash in the hallway or keep their volume down or something else minor.
