We, the Editors, are deep in the throes of the slush pile. It is a deep and dangerous beast, threatening to swallow us up. If you've submitted to us before, you know our reponse times can vary. A lot. This continues to be the case. (Sorry.)
In my forays into the pile, I realized I can be a bit impatient when reading a story. Thus I say to you: hook me!
Maybe this is an obvious tip but some writers seem to get lost in setting the scene. Or giving us the backstory of the characters. Or other looong setup details. Or extensive descriptions.
Don't do this!
Our culture has changed and it's faster-paced now than it was even a few years ago. Hook me immediately. This means your story has to start on the first page. This is particularly relevant for on-line 'zines. Readers want to be hooked immediately, so editors need to be hooked, as well.
