page title vs post title

is it possible to not show page titles on any page, but show the post titles on the blog page?

Currently I use a separate page template for my blog page:

<?php while (have_posts()) : the_post(); ?>

			<div <?php post_class() ?> id="post-<?php the_ID(); ?>">
                                <div id="poststyle">
				<h2 class="post"><?php the_title(); ?></h2>
				<div class="entry">
					<?php the_content('Read the rest of this entry &raquo;'); ?>
				</div>

this one allows the title, but for my regular pages, i comment out the h2 class post line of code. Is there an easier or better way to accomplish this? thanks
