Facebook at work at the Financial Times

The FT chooses Facebook@Work as its internal social network:

We want to provide our employees with a place to interact with each other securely and easily, anywhere in the world. We hope Facebook at Work will help further foster a culture of collaboration and a sense of community across our global workforce”, said Darcy Keller, SVP of communications and marketing at the FT.

Between Slack and Facebook@Work, I wonder how much oxygen is left for other enterprise social networks?

Mind you, either of them are better than the hell that is Sharepoint.
