Pittwitch, it seems they can do so rather easily, unfortunately. After all, as one person stated, prose and screen-writing are identical forms and require no alternative means of formatting.
Of course, that's complete bunk, but since the tripe is actually believed by someone, I'm quite certain that they also believe that using proper punctuation is neither wanted nor needed to communicate.
Considering the frequent miscommunication that occurs in society at large, one would think that the finer points of language would be at the fore of what the educational system chooses to impart. Sadly, however, it does not seem to be so. I can tell you that I saw a story a few months ago that attributed lines to a character that, had they been spoken by that character, made no sense whatsoever. The faux pas was the result of bad punctuation, which, yes, I did point out to the author in a review.
I shudder to think, though, that not only have the rules of grammar fallen to the wayside, but it also seems that broadening one's vocabulary is no longer considered a proper use of time. I can't even begin to tell you how many times I've read the same phrase repeatedly within the same section of prose. It's not only irritating, it's boring.
And, Bronx, surely you jest. Read a book? Why, there're movies to prevent that practice!
