I've had a story up at Pseudopod for a couple of weeks now. And it's been a delightful experience. I don't think I've ever gotten as much of a response for anything I've written. People have loved it, and hated it, (which is fine, because I love and hate nearly everything I've ever written) but what has filled me with awe is how passionate people have been in their reactions. People that don't know me, don't know my work, but have actually committed their time to experiencing my story, and Cheynne Wright's reading. And then they've felt enough of an emotional response to comment.
It's easy to write, and forget that people actually read(listen to) your stuff, and that they might actually engage with it. Easy and a little dangerous*. Silence is a terrible thing when you send your story out into the world. A terrible, terrible thing.
So, if you're writing horror, or dark fantasy I'd recommend giving pseudopod a go (and they pay promptly, too)
*Of course the reverse is just as damaging.
