By mixing and combining stanzas from different tweets in your timeline, Haikr not only creates haiku for you, but mashups. Distinct voices, events, and perspectives are remixed and re-cast in the space of your haiku generator. Part of the fun in creating a pleasing haiku with Haikr is seeing how the tweets of people you follow end up folding together into new statements.
So what exactly is a 'haiku'? Haiku is a type of poem with very tightly-constrained rules. Each haiku is three stanzas, or lines, of exactly five/seven/five syllables. This very specific format can require creativity, careful planning, and concise use of language to achieve a desirable effect — kind of like Twitter! The boiled-down, streamlined language of tweets is a fertile field from which to pull haiku stanzas.
