Could you quantify "quite popular"? I never heard of anyone doing that in my own circles, but know of such youtube vlog families, which makes me think it's probably around one in a hundred thousand (that would mean thousands of people from the USA or around a thousand in Germany, which would be like two orders of magnitude above how many people are successful doing it, which sounds about right)
