Acronyms are horrible things - they tend to create a layer of obfuscation that confuses new users, allow knowledge and understanding to diverge from reality (as original meanings get lost and forgotten), and can be used by some to imply some kind of knowledge superiority over their peers.  Unfortunately they are rife in [[#I|IT]] (!), and systems and techniques are often given unnecessarily long or complex names in order to create a ''good'' acronym...
