hey nib,
you can remove it using a custom page template, but as i see you are using Thematic, there is an easier way, just using the dynamic classes that are built into thematic.
in your main css style file…just add
body.page .entry-title {display:none;}
this will hide all titles from pages.
and the titles for blog posts will remain.
you can be more specific and just target certain pages
e.g
body.slug-about .entry-title {display:none;}
body.slug-web .entry-title {display:none;}
hope this helps
