This week you'll see us shift our application directory metrics to a focus on user engagement. This will help inform users as they make decisions on which applications to add as well as shift developer focus to engagement rather than total users. More specifics will be available as we roll out these changes this coming week.Recently, Facebook made two other changes to its Platform in order to prevent questionable tactics used by application developers to promote their applications. Developers will not be allowed to show a different profile to a user's friends than the one the user sees himself. Developers will also be blocked from sending misleading notifications to users in order to promote viral spread of their applications.
It's heartening to see Facebook is learning fast and making quick changes to ensure its evolving Platform continues to provide great experience for both its users and developers.
