So, if you were thinking that XP really means Perl experience, just forget it. XP is actually a mix of how a kind person you appear and how a smart Perl programmer you are. Maybe you would rather call it consideration, but unfortunately the word is already there for another use in the monastery.

Think of it as a Popularity Quotient. Hmm... I see the point of calling it XP now. PQ just doesn't have the same ring to it. ;-)

Update: See popularity.
