>, whatsapp groups became more important for social stuff at some point and FB loss significance.

I don't know a single person that uses Whatsapp and the only time I ever used was me and my former podcast partner (who was in Australia, 12 time zones away) and I used it to text each other. In average America Whatsapp is just not a thing, at least not for adults, nearly everyone has Facebook though.

Cultural difference - most of my friends in the UK and Australia (I have lived in both) use whatsapp as a primary way to talk to groups of friends. FB is more of an attention seeking thing and a place for your mum to see what you're doing.
