The major social networks have jumped the shark. Increasingly, social networks will be Balkanized into smaller interest groups. People won't leave Facebook or Twitter in droves but their attention will switch elsewhere as the zombie juggernauts become increasing desperate to hold our attention. (Facebook Messenger anyone? I thought not.) Photographers will share with other photographers. City networks will become more localized. Learning technologists will speak unto learning technologists.
Turning and turning in the widening gyre
The falcon cannot hear the falconer;
Things fall apart; the centre cannot hold;
Mere anarchy is loosed upon the world,
The blood-dimmed tide is loosed, and everywhere
The ceremony of innocence is drowned;
The best lack all conviction, while the worst
Are full of passionate intensity.
