shameless-plug: We've been building the federated/anti-yet-another-silo version of this/Slack. Instanced interconnect kinda like usenet did and email does for 30-odd years now.

Our emphasis on being a tool for developers to add federated communication to their app (vs being another silo like Slack). The UX isn't nearly as polished, but it does federate with other servers using the XMPP network (e.g a conversation earlier today http://imgur.com/UL34KSF).

A developer started working on a slack-like UX and we threw up at http://buddycloud.org (https://github.com/buddycloud/buddycloud-angular-app if anyone wants to help).
