What is Haiku Blogging?
Think about the haiku — the Japanese form of poetry of three lines and 14 (sic) syllables. It’s an extremely limited form of poetry, and yet it can be among the most powerful. That’s because the haiku poet is forced to choose only the most essential words to the concept or image he’s trying to convey. Only those words that will do the most for his purpose. The essential words.
