Yes, adoption is still an issue for us as it is in a pre-release phase and we have too many options (yammer, email, outlook groups, slack etc) but it's very promising. Once they officially launch it that will help (hopefully) provide a clearer product direction. It's pretty feature rich for an app in "preview". It's also free, and I like the tabbed experience. Bringing in Microsoft Planner, some document libraries and PowerBI makes for a pretty compelling story. Microsoft haters will never use it, but plenty of digital teams may get forced to use it if their IT team have already purchased Office365. And it's not that bad once you forget it was made by Microsoft. Slack ought to be worried.
