Do you have a problem with your right hands middle finger? You seem to double tap the comma...
no,,, it's just a thing I do,, Comma represents a pause, ,, I type on forums like i would a conversation,,, so multiple commas is a slightly longer pause between typing the next phrases,, ,, ,,,,,,, ,,
But all this is typed @ 90% speed,,, so ,, each comma represents, about 0.12 second pause
