Make those pesky authors write more:

 
function minWord($content){ 
 
global $post;
$num = 100; //set this to the minimum number of words$content = $post->post_content;
 
if (str_word_count($content) <  $num) 	    wp_die( __('Error: your post is below the minimum word count.') ); } add_action('publish_post', 'minWord');
