I'm a huge advocate of full-time remote working, but those like me who feel it is the future of work need to stop being so dogmatic about how communication should happen. I don't really like posts like this. Sure, it's a great idea in a remote context to write down how you like to communicate, and how you like to be communicated with at work. (You should do it, it's great!) However, not everybody will agree with you…
With remote work, you get the chance to rewrite company communication so that the above pointless meetings aren't needed.
People who write articles like the OP have realized that and view the former way to communicate as the extremely inefficient and intrusive system that it really is.
If you're in a fully text based async culture, then all the conversation, including the famous watercooler stuff and how're the kids doing stuff happens text based and async. I'd say the watercooler/kids stuff can happen more often, because you know you won't interrupt them when you ask, and they'll answer whenever they take a break.
Keywords are both text based and async. Not one, both.
