I did try to use Loom for this but the software kept running into issues so I deleted it.
I think as you said, that video adds personalization. I think it can also add an element of dynamism in an otherwise static course. Video can also sometimes demonstrates or express ideas or concepts better than other mediums. The issue is doing video well, which could take too long, at first especially, and also as you said, not all of us want to be on screen. If I used video, I wouldn’t have myself on camera but use images and video of other things with narration but then would that take even longer?
