The “flash fiction” site 365 Tomorrows is a collaborative project which presents a new piece of short speculative fiction each day. Contributions come from a combination of staff writers and select submissions from amateur authors around the world, and the site has posted a new piece every day since August 1, 2005.
The pieces are very short–the submission guidelines state 600 words or less–but there are plenty of stories in the archive: They’ll post their 1000th story this month.
This would be a good place to get a little taste of SF every morning, as well as get some exposure if you’re an aspiring writer.
