I don't understand why people keep saying it's not "easy" or IRC doesn't do history "well"? ZNC or another bouncer is plenty easy to set up and configure, and you get a full history of all messages in a chat. Slack didn't innovate, it simplified. I called it a "UI" simplification, but you can call it whatever you like. They didn't innovate on technology, and that's a dangerous place to build your startup, because someone like Microsoft can eat your lunch and there's nothing you can do about it.
