get latest article of a specific blog

Hi everybody,

I use the wordpress-mu-sitewide-tags plugin to display the latest articles of the entire network. Its a wonderful plugin!

Now I need a possibility to show the latest articles of my main blog at the other blogs. I tried this one but it does not work…

<?php $my_query = new WP_Query('blog_id=1showposts=1&cat=1'); ?>
<?php while ($my_query->have_posts()) : $my_query->the_post(); ?>
<?php the_title(); ?>
<?php endwhile; ?>

Nothing is displayed when I use this code. Is it possible to show the latest x articles of the main blog at the other blogs?
