Italics are good for that kind of ear/voice emphasis, as well, but in the context of FR general protocol, italics typically signify words quoted from another post. So in order to avoid confusion or the trouble of having to go through six key strokes required in HTML to create italics as opposed to zero key strokes to go all-caps, one "vocally" emphasizes a word by putting it in all caps.
You despise capitalization for emphasis. I despise people who get so hung up in silly minor crap like that that they change the entire discussion from something important, to something all about an ego (yours) and your choice to be offended by something.
Pathetic. You're angry about my pet peeve. Little person. I'm sure your word emphasis is REALLY important. Prat.
