	</c:if> 			 		
	<c:if test="${not empty podcast.fbPage}">
		<a href="${podcast.fbPage}" target="_blank" class="icon-facebook-producer producer-social"></a>
	</c:if> 			 		
	<c:if test="${not empty podcast.gplusPage}">
		<a href="${podcast.gplusPage}" target="_blank" class="icon-google-plus-producer producer-social"></a>
	</c:if> 
</div>
