Answer 1

Your curly bracket is being placed before the last echo statement, therefore the $r variable is out of scope.

Move the } to later in your page like so

<div class="message">
<?php 
    $sql = mysql_query("SELECT * FROM threads WHERE id = '" . mysql_real_escape_string($_GET['id']) . "'") or die(mysql_error());     
    while($r = mysql_fetch_array($sql))
    {
        $posted = date("jS M Y h:i",$r['posted']);
        echo $r['author']." ".$posted;
?>
<a href="http://twitter.com/share" class="twitter-share-button" data-count="horizontal" data-text="<?php echo $r['message']; ?>">
    Tweet</a><script type="text/javascript" src="http://platform.twitter.com/widgets.js"></script>
<div class="message2">
    <?php
        echo $r['message']; 
    ?>
</div> 
    <?php
        echo "Likes: ".$r['votes_up']."&nbsp;";
        echo "Dislike: ".$r['votes_down'];
    } 
    ?>        
</div>

Also notice the call to mysql_real_Escape_string in the $sql var. this will prevent nasty sql injections
