Congrats on your first video here. I agree with you here. These things can only explode when everyday people can see the practical use of a use case. Email, bitcoin, and even DTube. When your mother is using it, you know you're on a winner. Your audio is great, but be careful of the flickering background. Editing time can be reduced by scripting what you want to say beforehand (you won't move as much and you won't struggle for words).
