It's interesting that Yammer and Slack both exhibited many of the same "enterprise messaging rocketship" attributes. What's ironic is they are in similar spaces

It's interesting that Yammer and Slack both exhibited many of the same "enterprise messaging rocketship" attributes. What's ironic is they are in similar spaces. While correlation/causation issues aside, it seems to me that at any point in time, there needs to be a hot, "innovative" enterprise startup that captures the minds of people and wallets. The same thing will happen when Slack exits. I think this logic also applies to consumer messaging startups too. Communication and collaboration are massive needs that will always be around and need addressing. Edit: it's like a vacuum (as in, power vacuum) that needs to be filled by some entity to restore equilibrium to the world.
