The Slack Social Network

"Slack Connect is about more than chat: not only can you have multiple companies in one channel, you can also manage the flow of data between different organizations; to put it another way, while Microsoft is busy building an operating system in the cloud, Slack has decided to build the enterprise social network. Or, to put it in visual terms, Microsoft is a vertical company, and Slack has gone fully horizontal.

This doubles down on all of the advantages of shared channels. The user experience of chat specifically is what matters, the only reason this is even possible is because Slack is focused on one specific part of the stack, and the more companies that take advantage of Slack Connect the more of a moat Slack has. That’s the thing about social networks: their best feature is whether or not your friends are on it, or, in this case, whether or not the companies you are working with are using Slack."
