Override category archive page title (not the head title)

Not the best solution, but still works for my needs.

I used the category description instead, with h1 tags so that it looks like a heading. Then removed the taxonomy page title with:

function my_theme_archive_title( $title ) {

    return "";
}

add_filter( 'get_the_archive_title', 'my_theme_archive_title' );
