"Despite the “asychronous” claim, you have to keep a steady eye on it and reply in realtime or the conversation will move on without you."

For me, sync and async communication is a spectrum and chat (as it is used in the majority of companies) is more on the sync half of it.

I'm currently thinking about building a microblogging alternative to Slack, that will be more on the async side, not as much as email though.
