So - Path has a nice feature that lets you post pictures _through_ to Facebook, so for my friends who love Facebook, they can continue to post to Facebook through path. For my friends who have smart phones, but don't like social network, but like smart phones - straight forward - we finally have a reasonably private place for us to share stuff.

I'm not trying to convince more than half a dozen people to move though - so, don't really need the same uptake as Facebook.
