Strange Horizons is a very, very good online magazine that publishes scifi/fantasy/whatever short stories, poems, columns, and reviews. I've been reading them for years, and been submitting stories to them for years as well. No "yes" from them yet, but I have gotten some very good personal rejections from them as well, not just forms.
They've got 8 days and change left in the fundraiser, and are at about $7500 out of their baseline $15,000 goal. It would be really great to see them reach it! They've got some great things they want to do, like publish stories in translation, do interactive stories, that kind of thing.
If you haven't checked them out, go. Do so. Here are some things I've really liked recently that they've published:
Million-Year Elegies: Oviraptor, by Ada Hoffman
The Beef, by J.D. Moyer
Noise Pollution, by Alison Wilgus
little stomach, by Charlotte Geater
