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.
Like Me Date Me is a new dating site built on top of the Facebook Graph API, which provides search-able access to user profile information. The service displays a photo and limited profile information of whichever gender you want to see. As the name of the site implies, users can "like" others, which can then lead to more interaction. The ratings approach, encouraging snap judgments, is similar to HotOrNot, which also added an option to meet the people you rate.
