After four months, Facebook is set to open its timeline actions to developers this week, according to AllThingsD. The feature is an addition to the Facebook Graph API that allows developers to assign verbs for actions users perform within applications. For example, how users now "like" things, they'll also be able to "read" articles, "play" games and "listen" to music. I would expect many, many actions to be submitted to Facebook for approval, especially related to game-specific acts. It's too early to tell how closely the social network will watch its pending list of actions, though there's a clear approval process.
What would it mean to have a stripped down social network that was also secure? It would look like Tuenti, the social network out of Spain. To give an example of how seriously they take security, the Tuenti API is closed because "of our efforts to be the most private, secure social network on the market..." But if you play nice, they can make exceptions for commercial apps and games they have tested.
