Small social groups have always found a home online. It was called Usenet, internet forums, IRC, mailing lists, etc. The only difference with Slack and other stuff is that the user interface is slightly shinier.

Taking something that's been around (or known) for a fairly long time, throwing in a few buzz words and pretending it's a brand new idea.
