I cannot agree with this. You could very easily do that as a part of a form publications could fill out when they start using your app. You would simply ask the editors, as one of the possible ways to do this, to add tags to clarify what the publication is all about and what kind of stories it publishes. Then you would enable a tag search. For me, as a writer, that would make it much easier for me to find the publications that could be interested in my stories. This would also help other writers find my publication as well.
