Yeah, I would love for something like App.net to succeed, but unfortunately it probably will not. Even if every developer supported it, its the consumers who always have the last word. Consumers outnumber developers by at least 500:1, and 99 percent of consumers do not care about the issues that developers face. If you don't get consumers (i.e. non-developers) on your platform, it will die (unless of course you are building B2B tools or something).
