I am created a few Ning groups in the past but not anymore and though it was nice to create them, the communities quickly died because members did not contribute content. So I wonder if this was a general problem and if those ning groups you joined experienced the same problem?

Have used it occasionally to connect with people but never committed to creating groups I wanted to maintain.

Ning is an example of a good worthy technology that was just displaced with newer and more popular sites. Does anyone remember Copernic? I used to pay for Copernic search services back in the mid 90's and it was great. Now, most people never heard of them. They got displaced by Google.
