sidebar page div section | thematic theme

I have a custom menu for pages “Twitter” & “Facebook” – the menu is located in the thematic_betweenmainasides()

I want the user to be able to click on either of the pages, and for that page to display in a div section below the custom menu.

I alway want the twitter page to be the default displayed on the index.php\page.php

The code I believe will need to be a conditional if is_page(‘twitter’) || is_page(‘facebook’):

Does anyone have an example I can use? Much appreciated.

CURRENT CODEIN FUNCTION.PHP
function childtheme_secondary_content() {
?>
<div id=”socialfeeds”>
<div class=”widgetcontainer”>
<?php the_content();
edit_post_link( __( ‘Edit’, ‘thematic’ ), “\n\t\t\t\t\t\t” . ‘<span class=”edit-link”>’ , ‘</span>’ . “\n” ); ?>

</div> <!–socialfeeds–>
<?php

}
add_action(‘thematic_betweenmainasides’, ‘childtheme_secondary_content’, 10);
