Haikus...

Oh, the Haiku.  The most basic of all poetry forms, that most of us were taught how to write when we were very little but, I also feel that due to their short nature they have to be deeper and more creative than other poems. 

With prose poetry, the author doesn't have to conform to any one way of writing.  In those types of poetry, the words don't have to rhyme in any pattern, or follow any rhythm in terms of beats, so there is much more freedom as to the words that the author can use and the length of their poems equaling an ease in expressing the meaning of their poem.  With a haiku, the words have to fit into a rhythm so length of the words and the syllables used in them are limited; and I feel that because of these limitations on the format of the poems the authors need to be more focused on what they want to convey to their audiences in contrast to the authors of prose.
