Putting systems into System Testing

System - A group of interacting, interrelated, or interdependent elements forming a complex whole.  - http://www.thefreedictionary.com/system

People mean different things when they call themselves testers, and people think different things when they think about what it means to test something.  People generally distinguish between unit testing, integration testing, system testing, and user acceptance testing.  But what does system testing actually mean?  Why is it, when we're "taught" about system testing, noone ever explains what a system is?

"Exploratory Testing" is a pleonasm

It's time to stop talking about Exploratory Testing as a subset of testing.  There is no "exploratory testing" and "other testing".  All testing is exploratory.  If it's not exploratory, it's not testing.
