In "semantic-classes.php" at line 62 the code reads:
else : wp_title( '»', true, 'left' ); bloginfo( 'name' );
But I believe that a semi-colon is missing. Additionally I have found that the title appears better when 'right' is specified instead of 'left'.
else : wp_title( '»', true, 'right' ); bloginfo( 'name' );
Many thanks,
