Why? What’s the importance of what you’ve got to say?! Sometimes attention can be addressed more adequately by reflecting on the purpose.
IF YOU ARE NOT WILLING TO SAY SOMETHING IN CAPS THEN WHY SAY IT AT ALL?
Using caps is an option and I do use them sometimes, not to speak clearly though. I usually try to type in a way similar to the way I talk while stressing or highlighting using quotes. I would rather think of the reader while choosing my way of typing or words and use the most suitable way to deliver the message that I want to say depending on the meaning and context.
Were you in the army?! I know that my question might not make sense, that is the impression I get when I see that you are typing in caps because of wanting to speak clearly anyways.
