I will back up this share with a post soon. Ning which is SE clobbered EVERY site and search engine this month for traffic. SE sent about twice as much traffic as most social sites and beat out FB. To put that in perspective, I make about ten posts to FB (my pages, business pages, and groups) vs. one post on SE, and one of my posts w was featured on FB. SE still beat them ALL. Use SE for posts, videos, articles, and more, you will be glad you did. The traffic will surprise you.
