Our small company has been using Work Chat as an integrated part of our processes. We are bought into using Evernote Business and I feel have some serious power users in our organization. EN Work Chat has been a little clunky, but we've been using it more and more and it's been effective. Now, with what seems like the imminent demise of EN Work Chat, we are exploring using Slack. I'm glad to see all of the useful comments in this thread. Does anyone know what Evernote's plan is going forward for integrating chat with 3rd Party Apps like Slack? It would be helpful to share a note or notebook in Slack and then spawn the note or notebook in the EN native app on our desktop (OS) and apps (iOS and Android).
