I have Wordpress SEO by Yoast. But I want to make my images all pinnable, and the Yoast plugin doesn't have anything related to Pinterest from what I can tell. So after reading here, I added the Wordpress Social Sharing Optimization plugin. Does this mean I should take off the Wordpress SEO plugin? Also, I have the SumoMe Share now, but I'm not sure if I should. And, I have Simple Social Icons. I think I can get rid of some of these, maybe?
