Hey Haiku Nazis:
There are no set rules governing all Haikus. Rules vary across geography, language and culture. For the purists, Haikus that that actually follow the original "rules" are only those written in Japanese.
From the Haiku Homepage http://home.clara.net/pka/haiku/haiku.htm
"Haiku is a form of poetry popular in Japan, which is becoming more widely appreciated around the world in this century. Haiku writers are challenged to convey a vivid impression in only 17 Japanese characters.
One of the greatest exponents of this form was Basho (1644-94)
Three Haiku by Basho
Waterjar cracks:
I lie awake
This icy night.
Lightning:
Heron's cry
Stabs the darkness
Sick on a journey:
Over parched fields
Dreams wander on."
None of these translated Haikus are 5-7-5. Some Haikus are one-liners, others are written in vertical form. There are dozens of formats.
So before you go popping off and correcting others, you may want to get your facts strait.
