It's not clear Facebook have the formula for a successful new network - Instagram and WhatsApp were both acquired. When Facebook have tried to create their own new networks, like their original Snapchat clone, it didn't work. That's not really a knock on them though, I don't think anybody else could claim to be able to spin up a successful new social network either.
