Facebook soon to allow users to follow specific app actions

Facebook has just rolled out a new Open Graph feature that will allow its users to follow specific actions from various Facebook applications.

Now you will not have to subscribe or be friends with the user in order to get certain actions in your news feed. You can just follow what you want.

For example, you can decide to get notified when a user pins something to Pinterest and that will be the only item in your news feed from that person. It's like subscribing to someone's news feed, yet you are in control over what parts you see based on what app you are using.

This could really help businesses that use app's. What are your views on this?
