Writer's resource in need: Duotrope.com
If you're a writer and you're not familiar with [URL=http://duotrope.com]Duotrope[/URL], then you definitely should check it out. I haven't found a better online resource for looking up places to get your writing published. They cover everything from poetry to flash fiction to non-fiction to novellas & novels.
It's all free because of donations from the public, but lately they've been coming up short. If you can spare a few dollars, please consider donating.
(Mods: I wanted to put this in self-assignment but I don't have the permissions there anymore, please move this there if you deem it appropriate.)
