Strange Horizons is in the midst of its Spring Fund Drive. SH publishes some of the best new authors in the speculative fiction (science fiction / fantasy / magical-realism / etc) field. (I believe at least one of our authors has been on the Campbell ballot every year since we launched. And we got a Hugo nomination. And I know at least one of our authors has won a Nebula. And stories we've published have shown up in every major "Best Of F/SF/H" type collection. There've been nominations for the Tiptree and Spectrum. And so on.)
The magazine runs entirely on volunteer labor, but pays its writers pro rates (as defined by SFWA). That money comes from reader donations, and grants. Mostly the former.
If you're a fan of speculative fiction, please consider donating.
