How App.net can change everything.
Just read this article about App.net. It's pretty long but really good imo. I especially agree with this part:
In order to succeed, I believe App.net needs to show that it can effectively support multiple networks running on the same base infrastructure and data models, while being able to add their own unique attributes. Additionally, App.net needs to show that it can effectively manage permissions for the data that are shared within and across networks. To do this in the near term I suggest that App.net establish a secondary network for the developer tier of backers, which I called Dev above, and proceed to figure out the methodology for having developer user accounts operate concurrently on Alpha and Dev and how they can cross post between them while maintaining the overall privacy of the Dev network (which requires a different level of subscription payment than Alpha).
