waiting:
I know your question wasn't directed to me, but I would like to respond to it (and I look forward to Frenchy's response).
I have always found that writing poetry seems to be the purest way to express whatever it is that I am feeling.
Perhaps a poem is to a writer what a color palette and canvas is to a painter. A painter often sketches an idea in pencil before painting it, to rough in the content and perspective. Yet, no one would question the reason for painting it with color on canvas. There is where the sketch comes to life and becomes capable of emotionally moving the viewer, sometimes quite profoundly! Interestingly, the same painting (or poem) will often provoke different references and feelings in different viewers (or readers), becoming an interesting catalyst that takes on a life of its own, independent of the artist and whatever he/she was feeling at the time. Those works (which may include poetry and any other art) that do not fail to elicit some response in the viewer often become regarded as masterpieces. Most cultures and societies treasure those works of art that are seeded in their midst, and generally regard them with the highest esteem along side of any other worthily regarded accomplishments (artistic or not) that they may produce.
For me, poetry seems to allow a certain freedom and an ability to explore and voice thoughts and feelings that might otherwise not be as easily or naturally expressed. I often find that I come to really know my innermost feelings about whatever it is that I am writing, as a direct result of my efforts to give it voice in the poem. In this way, the writing process is cathartic in that it fills a very basic need that I have to know and express myself about something for which I care about.
If, as a result of my efforts, I create something that provokes in the reader genuine thought or emotion about the subject that is appreciated -- then there is also a wonderful feeling of creative accomplishment and validation, in addition to the personal catharsis. I believe that all individuals are seeking validation, albeit in different ways. For the artistic or creative person, that validation is also sought through the art.
Although, as this response shows, I also enjoy all forms of writing, including essays, poetry seems to best connect me to what I FEEL about something, as opposed to to just what I reason on the subject. For that reason, I believe poetry often captures the ability to emotionally move the reader in a way that other writing forms do not.
I guess, from your question, as well as what I have observed in others, I would conclude that many persons don't get the point of poetry. Since writing and reading poetry is so much a part of me, I find that difficult to relate to. I imagine that those individuals relate to life and their feelings in a different way. I also wonder if those individuals, have just not allowed themselves to relate in that way. Perhaps negative (or lack of) experience makes them uncomfortable with such direct confrontation with feelings and subconciously causes them to withdraw emotionally. Perhaps you or someone might care to comment on this.
I welcome any agreement or disagreement on this response. I enjoyed writing it -- hopefully you enjoyed reading it!
