I have yet to hear any girl complaining about guys who talk too
little.
Like what Canny says, let the girl talk all she wants.
After every 100 words, the guy just needs to go, "Really?"
or "Yep" or " Oh, I see "
A nod once in a while is also preferred. 
but i need to take the initiative to ask her something first
mah, some girls just uhhh too shy to take the initiative.
