As a developer it wouldn't be hard to implement this. Create a Facebook Login button which logins in with facebook but doesn't allow the post-as-me permission.

As a developer it wouldn't be hard to implement this. Create a Facebook Login button which logins in with facebook but doesn't allow the post-as-me permission. Create a separate button once they've logged in which says something like "I want to share this with my friends now" which would ask for the share-as-me permission. Or set up the dialog so that it only asks for the share-as-me permission when the app needs the share-as-me permission. I think this is more developers not putting enough thought into what permissions they actually need vs what permissions are nice to have.
