Which I only did after Drunk Dave started talking about PSU's - i.e. *I* didn't change terminology. You're wrong. Again. For the millionth time.

I aggee: Whisky-dave started talking about Power Supply units before you did. But after talking about power supplies you latched on to power supply units and started talkking about them instead.. i.e. you changed the subject.

Sandman
Sigh, you really can't be this stupid, Eric. No one can. So if I get this right - another poster starts talking about something and if I respond to him and talk about the same thing he is talking about - then *I* have changed the subject?

Eric Stevens
You have changed the subject you are talking about.

Try http://en.wikipedia.org/wiki/Semantics

Sandman
First sentence: "Semantics ([...]) is the study of meaning"

"Linguistic semantics is the study of meaning that is used for understanding human expression through language"

I couldn't find anything that said that "it's not" about word meanings. You know, like you explicitly claimed it is.

Unfortunately the authors of the Wikipedia article didn't know you were coming.
