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.
