Do you think haikus are poetry? I personaly do not. I see poetry as someting that can tell a story in some sort of format, haikus can't tell a story (well, rarely can) in the specific haiku format. I like haikus and all but I don' see how they are poetry.
If you don't know what a haiku is, it is a "form of poetry" where the first sentence has 5 syllables, the second has 7 syllables, and the third has 5 syllables. Here is an example.
Hello sunny day
Bright sunny blue sky above
Under bright light
(You can see, this really tells no story)
