Will Facebook Users Share Their Email Address with App Developers?

As part of Facebook’s Platform roadmap rollout, applications will no longer be able to send notifications to users – instead, Facebook is creating an new API through which users can explicitly deliver their email addresses to developers, and also creating a new counters for developers to show on app bookmarks. Because many developers have used notifications to send both user-to-user and app-to-user updates, this is obviously going to mean big changes for some applications.
