1. Create a child theme so that you don’t lose your changes when upgrading wordpress.

2. Add the following code to change to your custom value. My situation called for a ‘more’ link. Put in whatever text/markup you want. This code first removes the excerpt ‘more’ filters from the Twenty Ten parent theme. Then it replicates the functions and makes a call to its own function where you can control the ‘more’ text/markup.

Notes: To remove the more link altogether, just use the top 5 lines and leave out the duplicate functions/add_filters below. To increase the excerpt length, add your own excerpt_length function and filter and remove the twentyten_excerpt_length filter.

add_action( 'after_setup_theme', 'mc_setup' );
function mc_setup() {
	remove_filter( 'excerpt_more', 'twentyten_auto_excerpt_more' );
	remove_filter( 'get_the_excerpt', 'twentyten_custom_excerpt_more' );
}

function mc_auto_excerpt_more( $more ) {
	return ' …' . mc_custom_more_link();
}
add_filter( 'excerpt_more', 'mc_auto_excerpt_more' );

function mc_custom_excerpt_more( $output ) {
	if ( has_excerpt() && ! is_attachment() ) {
		$output .= mc_custom_more_link();
	}
	return $output;
}
add_filter( 'get_the_excerpt', 'mc_custom_excerpt_more' );

function mc_custom_more_link(){
	return '<div class="excerpt-more"><a href="'. get_permalink() . '">' . __( 'more') . '</a></div>';
}
