How to Make a Video for Public Speaking

I feel like this is maybe changing too, at least for me coming from a very non-remote job before COVID. And then obviously everyone's remote during that time and it's shifting back now. I forget sometimes that recording a loom video is something you can do outside of your full-time job for other people on the internet. It seems so casual and easy. But it doesn't have to just be internal and you could even just quick walk through videos of something to show publicly on your personal site. So I really like that idea.
