Ooops, so I did. Ah well, hopefully people will figure it out.
I think a lot of people type in ALLCAPS when they want to emphasise something. But, I think Necroman's post makes a great example of why italics are better. Consider these two lines:
I have a personal opinion
I have a PERSONAL OPINION
Both emphasise, but the second is also like.. "ummm... chill out dude, no need to get hostile!!"
