Serious question, is anyone here on HN still actively using Facebook (not WhatsApp or Instagram)? Maybe I live in a bubble, but I literally don't know a single person, young or old, who still uses Facebook. Based on my personal experience I don't understand how this social network still has any relevance?
I use it mainly for fb groups 1. flat n flatmates groups - when moving to different city, this by far is the most efficient way to find genuine flats and flatmates (you can see the background profile of person which gives you some context). 2. to join niche communities like Notion group on fb.. kind people there helping each other out. I love hanging out there.
Some had commented in the past that they still use some groups to interact with their local community (think parents and the school of their children). It was on HN so I guess it was in the US?
Other features that are still relevant: the marketplace, events, and pages from businesses where complaining can actually lead to an answer. This year I was waiting for refunds from some sport events, and the only way for me to get some updates or at least know if other customers were happy with a 30% refund (!) was to check the Facebook page of the business. Businesses have a bigger pressure to answer since it's public: no answer to a lot of angry comments is bad for them.
Facebook itself has lost relevance (though almost everyone I know has an account, even if they don't use it as much), but Facebook's other properties like Instagram or Whatsapp are still very popular.
