Ok, Grumpy Gus,

Though I can't claim to be an expert on poetry, I am currently in a class based around it, and I think the main purpose of peotry is to convey an image, however twisted or droll that image may be. Poetry is a means of expressing one's artistic thoughts. In certain types of free verse, a poet can use a word here, a large space, a couple words here, another in all capitals here and make some sort of idea pop into the readers head. Spacing and using all lower case can be effective in certain ways. It may not be nicely organized and traditional, but it can get it's point across.

And, just to make sure I relate to the topic: dementia praecox.
