Karen Woodward writes some tips on choosing titles, with explanation in each section. Have a look; if an editor is running through a list of 50 stories she might start by reading the five most interesting titles first:
- Easy to remember
- Indicates Genre
- Is Funny
- Tips For Brainstorming The Perfect Title
The last one is a summary of another writer's blog post on the topic, and she rounds the article off with a list of great titles.
