"Our focus is on works of fiction or poetry that can be enjoyed during a 20- to 30-minute public-transit commute to work. And because we know your taste in reading material is varied and sophisticated, we plan to surprise you by selecting samples of not only literary fiction, but sci fi, fantasy, horror, mystery, thriller, romance and experimental combinations thereof."
Fiction submissions should be 500 to 4,000 words, but I'd guess that, for a mobile devices like a smart phone, the shorter, the better. Also, twice a year, they plan to publish The Best Of CommuterLit.com in hard-copy form.
