This is probably not a terribly original observation on my part, but Extreme Programming is horribly misnamed. I don't view it as particularly extreme: it merely says "follow the good programming practices that you already know about". What, if anything, is extreme is that it tells you how to follow those good programming practices.
The big problem I have with the name, though, is the implementation detail embedded in the name. "Programming" shouldn't be there. XP is about project management, not about programming per se. If you took out the programmers and said "carpenters should review each others work, not build things the customer didn't ask for, get frequent feedback from the customer, etc.", then many people would shrug and agree. If anything, it should be called XPM: eXtreme Project Management. However, since I don't think it's extreme, I suppose we could call it Really Good Project Management, but RPGM just doesn't have the same ring to it.
