Try this:
$('.main ul').each(function(){
var $this = $(this), lis = $this.append($('<li>').text('More').click
(function(){
lis.toggle();
$(this).text($(this).text() === 'More' ? 'Less' : 'More');
})).find('li:gt(9):not(:last)').hide();
});
Since you have more than one '.main ul' you'll need the .each you had
to keep the li's separate. Using li:gt(9):not(:last) selects any li's
at index 10 or above (zero indexed) and hides them, excluding the last
li which is the newly added link for more/less.
Since the link doesn't go anywhere, you're not creating a usability
problem by assigning the click event to the li itself (although you
can add an anchor and adjust the script accordingly if desired).
