So do you use your right or left thumb to press down the spacebar?

Let's see. I don't know. It's hard to yes, I do. I use my right index finger too acro-nym. =o

I played with a few typing programs back when, but failed miserably at them all. It sucked that you had to have perfect accuracy, and if you fucked up, it'd freeze you there until you fixed the mistake. So you have to basically put a brake on your mind, reverse back, backspace and continue. It wastes so much time. There's proof-reading for a reason.;_;

I did the hunting and pecking thing until I got aim. Then I had to keep up with people, and I gradually grew familiar with the keyboard, and now I basically use homerow typing, kind of. I mean, I use it to position my hands, but otherwise, it's just I know where all the keys are. =o

Jam it back in, in the dark.
