Resolved this:

    <<<<<<< HEAD
        $('.overflowed img').live( 'mouseover', function() {
        Libertree.UI.showShowMores();
    =======
        $('.home #river-selector').change( function() {
        window.location = '/home/' + $(this).val();
        return false;
    >>>>>>> origin/vertical-posts

by keeping both blocks.
Fixed pixel width for excerpts, so that there is not a big gap between the left of the excerpts and the right of the sidebar.
Apply shadow (back) to excerpts listing.
Apply little rounded corners (back) to excerpts area.
