"All of these may have previously signalled novel thought, and now anyone that's really savvy does their best to not use the phrases because they know how tacky it makes them look, even if they actually use them in meaningful ways."
I found this a quite humorous paragraph shortly after you had spouted things like "Not Repeat Yourself" and "Test First Development". Maybe it somehow doesn't apply to all those XP phrases? ;-)
