Valid HTML Question
Just a question for the developers of add this why not instead of using non valid attributes like g:plusone:size="medium" and fb:like:layout="button_count" convert those to valid html5 custom data attributes like <a class="addthis_button_facebook_like" data-fb-like-layout="button_count"></a>
i would assume it would take very little work and would allow for more respect of web standards.
