> Avoid email or WhatsApp as much as you can. They are private by nature and make it harder for people to jump in if needed. Hallelujah! To extend upon that, I think companies should pick one medium for internal communication and stick to it. Doesn't have to be Slack, but it can be Slack. Keep email for external communication, of course. At every company I've worked some people would start threads in Slack and others would start them through email. This is a pain in the ass because now I've got to pay attention to 2 programs and email is just generally inferior for group communication.
