Twitter needn’t be inane or just about self-promotion. One PR problem that poetry faces in this country is that it isn’t a part of people’s everyday lives. The only time poetry is brought to them is when it is on an English class syllabus. Twitter changes that. Poetry can now come to people on their cell phones.
Haiku is an ideal form for Twitter for two reasons–it’s compactness and its clear language. To the everyday person who hasn’t seen a poem since they read Robert Frost’s “Stopping By Woods on a Snowy Evening” since high school, haiku looks like it’s meeting them halfway. (“At least it doesn’t rhyme!”)
So they are willing to meet it in the middle. Hence the invention of the “Twaiku” (haiku + Twitter) and a resurgence in the interest of haiku itself.
It doesn’t have to be just about networking or marketing, Twitter can also be a poetic experience.
