Could I get a list of online magazines and sites that pay to buy short stories or poems? Like Strange Horizons, for example. I'm interested mainly in those who cater to the science fiction, fantasy, and romance genres, but others are also welcome. Thanks!
All you really need is www.duotrope.com There are a few I can recommend, but you can find most markets on there, and check them out for yourself.
I think we just had this thread, check some of the recent threads--you should find something similar.
