Adding passing acquaintances on Facebook has actually made them developing into real friends more likely by my anecdotal reckoning, as they're at the top of mind my when I see their updates and I remember to check in.

And my partner being friends with my mum on there has actually helped both out with subsequent interactions as they know more about their common ground.

Facebook, ultimately, is what you make it. There's loads of "racist uncles", "fake news", "Tasty videos" etc, but if you engage with the people, it's as powerful as ever.
