I recently went to a sort of editor-fest where I got to see a bunch of editors at work. The thing that really struck me was: editors are very subjective. I rarely agreed with the other editors and they rarely agreed with each other. Thus, market is a very important consideration. Each 'zine is a different market. Each 'zine's editor has different subjective opinions. Therefore, it is to your advantage to become familiar with the markets before you submit to them. With Electric Spec it's easy and free! Just click and start reading!
There was also a discussion about why authors should bother submitting to 'zines in this age of self-publishing. You could self-publish your stories--and in some cases that's the best option. But if you publish with Electric Spec, you'll reach a different group of people than you would otherwise. We have a built-in audience. And we include your bio info and archive you story on our website, so people can always find it and find out about you.
Moreover, at Electric Spec editors work with authors to make their stories the absolute best they can be.
So, send those stories in!
