I don't use home row, but that's just because I was never taught to. I tried learning it, and just found it to be really difficult. I type really fluidly, using almost all of my fingers, kinda like a home row-user would, but my hands basically work freely. I suppose I've subconsciously trained my fingers to go to certain keys without having to learn a specific ways of doing things. I tried learning home row earlier this year, but it's like trying to re-teach yourself how to breathe, walk, chew food, etc. It just doesn't work.
I use all digits on both of my hands. I use my little fingers almost exclusively for the shift key and other keys pushed really far to the left or to the right. I don't use my thumbs for the Spacebar like you're "supposed to", except for sometimes. I only use my thumbs for the spacebar, but I rarely even do that. I usually use my other fingers for the spacebar.
