I've come to the realization that my fellow editors and I have different taste in spec fic stories! What does this have to do with me, you-fabulous-authors ask? A lot. Here at Electric Spec editors get assigned stories randomly. So, it's just the luck of the draw which editor you get, and your story may or may not be among their preferences--or pet peeves. I'm sorry about that; it's not fair.
Another thing that's not fair is: you can have a very good story, even a great story, and if it doesn't fit what we happen to need, we'll reject it. :(
All authors run into that problem. Personally, I'm planning on writing FOR specific markets in the future.
Anyway, the point I wanted to make is, please don't let anyone--certainly no editor (or agent)--discourage you from writing! Good luck!
