Je ne me souviens jamais des liens « share » des rs, je met ca directement sous forme de liste avec sprite.

<?php
$myUrl = 'http://omercrafts.com/dev';
echo '<nav class="rs">
 <ul>
 <li><a class="twt" target="_blank" href="http://twitter.com/share?url=' .$myUrl. '"><span class="icons-twt"></span></a></li>
 <li><a class="fb" target="_blank" href="http://facebook.com/share.php?u=' .$myUrl. '"><span class="icons-fb"></span></a></li>
 <li><a class="pin" target="_blank" href="http://pinterest.com/pin/create/link/?url=' .$myUrl. '"><span class="icons-pin"></span></a></li>
 <li><a class="gp" target="_blank" href="https://plus.google.com/share?url=' .$myUrl. '"><span class="icons-gp"></span></a></li>
 <li><a target="_blank" rel="nofollow" class="in" href="http://www.linkedin.com/shareArticle?mini=true&amp;url=' .$myUrl. '"><span class="icons-in"></span></a></li>
