Check out #ThursdayTales, a new reader-generated feature at io9 that started yesterday. A group of io9 commenters, led by the formidable Gaudy Mouse Muad'Dib, started a severely cool new practice of sharing links to new short stories they'd written. After just one day of #ThursdayTales, there's already a wealth of incredibly cool short fiction. Can't wait to see what everybody comes up with next week!
When you post your stories, be sure to say if you want critical feedback - let your fellow io9ers help you revise your work and make it better! I know from long years of experience that getting a critique always helps me change my work for the better. (Unless the critique is something like "you're stupid," in which case - well - there's just no fixing that.)
