I like to have the excerpt used in the og:description tag if viewing a single post. So I made the following changes to the function opengraph_default_description:
function opengraph_default_description( $description ) {
if ( !empty($description) ) {
return $description;
}
// Use the blog description if we are not looking at
// a single page, or no excerpt exists.
$description = get_bloginfo('description');
global $post;
if ( is_singular() && !empty($post->post_excerpt) ) {
$description = $post->post_excerpt;
}
return $description;
}I personally think this should be made the default in the plugin source.
