@JPB,
In that case, you'd be interested in this latest change they've made:

Excerpt:
Previously, you've had the ability to hide an application story, or block it completely. Now, we're putting changes in place so game stories only post to your feed if you're playing them. This means people who play games can post stories to their Wall without worrying about overwhelming their friends who aren't playing, and people who don't play games won't see irrelevant stories in their feed for which they have no context.
For game players, here are some improvements we're excited to be launching today:
* Full stories in News Feed so they won't miss when a friend shares an action or needs help in a game. The more active a person is in a game, the more prominent the stories will be.
* Smarter bookmarks on the home page that will automatically appear and reorder based on the games they're playing. They will no longer need to individually bookmark apps, and it will be easier to get to favorite apps.
* A clearer, highlighted number for pending requests or tasks alongside bookmarks.
* Requests in the Games Dashboard, where they can manage all their game activity and discover new games.
People who do not play games will only see stories when a particular game is added by a group of friends, instead of ongoing News Feed stories. These dedicated stories will show which friends are playing a game, making it easy to join them. Over the coming months, we plan to launch additional features that provide improved and personalized social games and News Feed experiences. Happy gaming!
