My flash-fiction story "Canvas" just sold to Daily Science Fiction -- my first pro-paying sale. I'm pretty jazzed about it. DSF is a great magazine. Subscription's free, and every weekday they e-mail out a story. They also keep an archive of all of these on their website. I'm not sure when my story will actually appear, but I'll be sure to let you know.
My favorite living short story writer, Eric James Stone, has a number of stories published in Daily Science Fiction, which made selling "Canvas" even better. If you haven't read anything by him, I highly recommend it. I was terribly excited when he won a Nebula this year. His bibliography contains a truckload of his work available either for free through magazines like DSF or free via audio podcast.
