I see Facebook as the one most likely to struggle because, at least in the UK, Facebook the site is disliked by tons of people and is now mostly used day to day by older people. I don’t know anyone that is my age that actively posts on it anymore. Most people only keep it to keep in touch with older family who don’t use anything else. On the other hand, Instagram is very popular and so is WhatsApp.
