With the rise of Ning 3.0, many new possibilities have presented themselves in respect to ways of displaying and repurposing content never before possible with Ning 2.0 or 1.0.  And althrough there are many new obvious challenges for Ning network creators to overcome, the PROs outweigh the CONs.  In fact, I am finding that the opportunities for building engaged communities on Ning 3.0 are seemingly endless.  As an example, let's consider rethinking how we integrate social media plugins from outside of Ning into our networks.  We have Like buttons, comment boxes and share gizmos which allow us to share and vote for content on a web page even when outside of facebook. Great for a user, but not for a brand.  Said brand's ambassador must physically leave our site and over to Facebook to see their latest likes and posts. What if said brand manages active social media profiles on Twitter, Google+, Instagram, Tumblr, Blogger, Pinterest, Wordpress and Youtube, in addition to Facebook? Seems hard to imagine they would ever have time to go to your site when their time is mostly spent in between social media profiles.
