You have to keep reading, but you'll find I've touched on this - here a while back.

The problem seems to lie in the fact that the person to whom one addresses a message on the internet may not be the sole reader...no matter how private the forum. For example - had we had the internet then, a person referred to in a 1920s comment on Facebook as, "...a sweet, happy-go-lucky, gay man" would not be read as a sweet, happy-go-lucky, cheerful man today - but a sweet, happy-go-lucky, homosexual man. Language evolves. Or languishes. And we don't know which way any word or phrase will go.

My next rant will probably be on diction. D i c t i o n: The deliberate pronunciation of those words we are trying to express aloud and in song... (Don't get me started!)
