Slack, I’m Breaking Up with You
Samuel Hulick

Communication within an existing productivity app that allows for discussion around existing ideas, teams, users, projects and tasks would provide a better solution.

I believe Asana has the most potential to provide this service. However it needs to improve its current communication feature set, perhaps even developing its own external ‘slacklike’ communication app or chrome app that allows for hypertext mentions etc.

Unlike Slack, Asana is more user focused allowing for communication with multiple external users, teams & partners etc without switching profiles.
