I've finally finished with Ning. I was a big supporter and advocate for Ning. I created 7 Ning sites for nonprofit activities at no cost to them and one site for a client company. They are now all gone. The largest one was transformed into this blog. Four of them were just canceled. Three of the nonprofit sites have been resurrected with Grouply. The whole process has taken about five months, and a lot of my time, none of which I was paid for, and $180 from my pocket.
If other web 2.0 software follows this path, the web 2.0 movement will suffer greatly.
