I agree, caps are useful, but they are way overused. Yelling can be implied with an exclamation mark, and emphasis can be implies with italicized text, like I just did, but I have used them in trnascripts a few times.

Multiple exclamation marks is just too illaterate, and there's many times a simple period is fine. While they're an excellent tool, exclamation marks shouldn't be overused. I've seen many times people using them when the character didn't even yell or "exclaim" something.
