My story 'Ovoids' is up at Nature's Futures, and there's also a podcast. This is a new initiative from Nature. I think the editor, Dr. Henry Gee, did a great job reading it. But, hey, I'm biased.
Nature's Futures takes flash science fiction stories. It's a SFWA accredited venue and they send you 90 squiddles. Guidelines are here. You may also like to check out the podcast when Dr. Gee talks about Futures. Interesting listening.
