Pinterest now directs more referral traffic than Facebbok and Google+ combined. Before this week you could not add a Pin button to a Ning network, now you can if you add it to a Wibiya toolbar. I have two networks that now have pin buttons and traffic has increased by 20%. Highly recommended! In the screenshot you can see it on the bottom toolbar.
Thanks for the!
My pleasure Thiago. Amazing the difference it makes, especially if you have a network that uses alot of images or if you have products to sell.
