Display post excerpt from specifc category

Learning about using multiple Loops is the best way.

Thanks Moshu, I managed to put a solution together that worked:

<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<!-- If the post is in the category we want to exclude, we simply pass to the next post. -->
<?php if (in_category('6')) continue; ?>
<div class="post">
    <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
    <small><?php the_time('F jS, Y'); ?></small>
    <?php
	$strings = preg_split('/(\.|!|\?)\s/', strip_tags($post->post_content), 2, PREG_SPLIT_DELIM_CAPTURE);
	echo apply_filters('the_content', $strings[0] .  $strings[1]);
    ?>
</div><!-- closes the first div box -->
<?php endwhile; else: ?>
    <p>Sorry, no posts matched your criteria.</p>
 <?php endif; ?>

Now I just need to find out how to limit the output to 3 posts.

<?php $my_query = new WP_Query('category_name=Blog&showposts=3');
  		while ($my_query->have_posts()) : $my_query->the_post();
  		$do_not_duplicate = $post->ID;?>
    <div class="post">
  		<?php //the_permalink(); ?><?php //the_title(); ?>
 		<a href="<?php the_permalink(); ?>"><?php the_time('F jS, Y'); ?></a>
  		<?php
			$strings = preg_split('/(\.|!|\?)\s/', strip_tags($post->post_content), 2, PREG_SPLIT_DELIM_CAPTURE);
			echo apply_filters('the_excerpt', $strings[0] .  $strings[1]);
		?>
	</div><!-- closes the first div box -->
  <?php endwhile; ?>
    <!-- Do other stuff... -->
  <?php if (have_posts()) : while (have_posts()) : the_post();
  if( $post->ID == $do_not_duplicate ) continue; update_post_caches($posts); ?>
   <!-- Do stuff... -->
  <?php endwhile; endif; ?>

sorry about the indenting
