The use of "extreme" in the name is partly supposed to
convery the "in-your-face" attitude.
XP takes previous approches to software development and
turns them around completely.
From the stories that I have heard of
Kent Beck
teaching
people about XP, he's very extreme as well. Very
entertaining stories. In a post grad course I took, we covered
XP in one lecture. My
lecturer
took an extreme approach to teaching it, which made the
lecture a lot of fun and carried across Kent's attitude.
I've picked some of this up
as well,
so I don't talk about extreme programming, it's EXTREME
Programming!
