Async video can be powerful.

Communication runs the gamut from the written word (emails and chats), to the spoken word (voice calls), to video (Zoom and YouTube). There are simple and free ways to record your screen with audio on both Apple and Microsoft platforms, and it's a great way to convey complex ideas to a distributed group asynchronously. It works great for point-to-point communication, too: instead of sending your colleague a lengthy email to try to explain something that's inherently visual, try capturing it as a short video and sending it that way.
