Latest 5 post excerpts from 5 different authors in Sidebar

Think I’ve figured it out. Here’s the code I used courtesy of this thread on the WP Support Forum. Just replace ()<?php the_author_posts_link(); ?>()
with whatever excerpt code you want to use. And Voila!

<?php
//list 5 latest authors
$authors =  array();
$count = 0;
$args=array(
'post_type' => 'post',
'post_status' => 'publish',
'posts_per_page' => -1,
'caller_get_posts'=> 1
);
$my_query = null;
$my_query = new WP_Query($args);
if( $my_query->have_posts() ) {
while ($my_query->have_posts() && $count < 5) : $my_query->the_post();
$author_id=$my_query->post->post_author;
if (!in_array($author_id,$authors)) { ?>
<?php the_author_posts_link(); ?>
<?php $count++;
$authors[]=$author_id;
}
endwhile;
}
wp_reset_query();  // Restore global post data stomped by the_post().
?>
