100words.com is a web site that challenges writers to write 100 words a day for a month. Writers can then upload their batches to the web site to share with others. Site creator Jeff Koyen explains:
This is an exercise in disciplined creativity. Writing exactly 100 words at a time — not a single word more, not a single word less — isn’t as easy as it sounds. The word count may be arbitrary, but the motive is not. To borrow from Proust, the tyranny of rhyme often brings out the poet’s best work. By working within a standardized form, the writer can concentrate on other matters.
Flash/micro fiction fans might consider taking Koyen up on his challenge or just visiting the site to explore some of the uploaded works.
