Hi Tony! We had a lot of fun - I think folks were nervous about coming up with something... but once we got started, the thoughts just flowed.
I'm sure that you've seen Echoing Green (one of our associates came across their website on a research task) and they've really taken the wdydwyd ball and run with it: http://www.echoinggreen.org/. I love it.
I like this Ning platform - I read about the company in Fast Co. this month. I'm going to keep adding to CWV's page and spreading the word.
