So this is big:
Around the same time we started building Slack, another team began building their vision; a service specializing in voice, video and screen sharing that would allow people working remotely to work as if they were in the same room, and people in the same room to work better than ever.
That team was Screenhero. And the more we got to know them, the more we liked the cut of their jib.
According to Slack, the plan now: integrate Screenhero into Slack. That's voice, video, and screen sharing…in Slack. That could be pretty amazing (well bad for Skype, amazing for everybody who hates Skype).
