Thematic theme: get rid of postmeta and postfooter on home page only

Hi there, I have asked this over at Thematic, but nobody seems to be available for help. I am a lousy programmer/scripter, but I excel at copy/paste code :-).

What I want is to get rid of the postmeta and postfooter stuff on the home page, but leave it intact on single post pages. What I did was the below and it’s not working, and I can’t figure out why not:

function no_thematic_postfooter() {
  if (is_single()) {
    global $id, $post;

    if ($post->post_type == 'page' && current_user_can('edit_posts')) { /* For logged-in "page" search results */
        $postfooter = '<div class="entry-utility">' . thematic_postfooter_posteditlink();
        $postfooter .= "</div><!-- .entry-utility -->\n";
    } elseif ($post->post_type == 'page') { /* For logged-out "page" search results */
        $postfooter = '';
    } else {
        if (is_single()) {
            $postfooter = '<div class="entry-utility">' . thematic_postfooter_postcategory() . thematic_postfooter_posttags() . thematic_postfooter_postconnect();
        } else {
            $postfooter = '<div class="entry-utility">' . thematic_postfooter_postcategory() . thematic_postfooter_posttags() . thematic_postfooter_postcomments();
        }
        $postfooter .= "</div><!-- .entry-utility -->\n";
    }
    // Put it on the screen
    echo apply_filters( 'thematic_postfooter', $postfooter ); // Filter to override default post footer
    }
    else {
    return ('');
    }
}
add_filter('thematic_postfooter', 'no_thematic_postfooter');
 // end thematic_postfooter
