depends on what I'm typing. (Score 1)

Often if I'm just typing one word, I'll use 2 fingers. For a username and pass, I'll use 4-5 fingers; browsing the web I use 5. typing a quick sentance or two I'll often use 6-7, mainly my right hand but filling in weird letters and caps with the left.

And then, if I feel like wasting everyone's time, I'll type a paragraph; that uses 9 fingers.
