Has anyone used Ning to promote their business?

I heard someone say that NING as a social network has some essential publishing tools that can help you promote your business. Browsing through it i come across these features...........
.Publisher Blog with content categorization, lead photos, and built-in SEO
Invitation features where you can welcome other experts or members to co-publish
An optional member blog feature
Prioritization feature where you can use Facebook, Disqus, or native Ning comments
and Email Broadcast capability
Mostly I have used Facebook to promote my products, services and blogs and have never tried the NING thing before but am willing to use it if advised otherwise. Has anyone used it before and if Yes how perfect does it work?

Never even heard of it before. I'll consider looking into it in the future. The fact that I haven't heard of it yet makes me wonder how effective it can be without having established brand awareness yet. Maybe I'm out of the loop though.
