Now that Duotrope charges for its services, I've decided to write up the database of short story markets I've come across in the past and put them on my blog. These ones are for genre/speculative fiction (I'll do my general fiction list soon), and all pay and accept submission via email or an online submission form. Hope some of you find it useful!
