Yes, that is inevitable. Growth is slowing down for FB and the platform has grown to the size where it can't pivot hard. Any new player in the marketplace simply has to reject FBs success and present a wholly different way of interacting, free of the all-inclusive strategy employed by FB.

One thing we are seeing a bit and may see more of is microplatforms. They will focus on specific interactions instead of the generic type FB goes for (thinking bangwithfriends (some would even say Tinder is this type of SN), sector-specific Linkedin, regional social networks).

FB will be around for a long long while thou. It was a twist of genius implementing federated logins, in effect becoming your passport to the internet.
