How many of you are Extreme Programmers?

[Mike Brenner]

Most of the previous answers stated that they
do the continual and thorough testing portion of XP.

Continual and thorough testing was not new to 
XP, and XP did not invent that. We, too, do a lot of that.

To be Xtreme, you also need to overcome the social barriers, 
quite a difficult feat. Getting people to see the advantage,
for example, of two people working together at all times
is challenging (to the territorial ego of almost all
developers).
