I used to have sort of the same issue with Ning as I did with pre-launch Xobni, which is that descriptions failed to make clear exactly what the prodcut does.

I used to have sort of the same issue with Ning as I did with pre-launch Xobni, which is that descriptions failed to make clear exactly what the prodcut does. They're both pretty clear now, but you're right that for most people, there doesn't seem to be much reason to use Ning. I could see it gaining some traction with corporate intranets, though, especially with a focus on content sharing.
