It doesn't really default to anything - except quoting the 
original text.  It's just that when you start out, your cursor 
is at the top of the quoted material.

 From there you can either review and edit the quoted material 
(which you should do anyway)

If you don't want to review the quoted material, hit Ctl-End to 
go directly to the bottom and begin typing.
