Chris Brogan has been experimenting with a new social network called ‘grasshoppers’ – people helping people. He has created it in two places: Ning and Facebook (although it did seem to migrate through Google groups quite quickly on the way to Ning).

It will be interesting to see which one is preferred. I like Ning better as I’ve been participating in other groups on that platform and it is very easy to use.
