Disjointed English for effect

[Leanne]

Now that works largely because the one single capital stands out, which is pretty much what I mean about using un-grammar (it's a word now, dammit) for emphasis.

Writing "both ways" is good advice -- I tend to write everything out "properly" first, then take bits away as it suits me (although often I leave end punctuation to last, to see how it will affect the flow of the final product).
