Facebook – How to show someone who you previously marked for Facebook to hide from yours news feed

It does not seem to be possible. There is chatter in the Facebook Support Community but nothing to suggest that it is a feature right now.

There was a time where you could at least have priority of the filters by dragging but that seems to have been removed in the redesign.

For now until Facebook brings it back , you are going to be stuck with a add-on like Feed Filter or just stick those people you know use mafia wars into a Friend List .

Can I "like" a TV show on Facebook but not see news from it in my News Feed?

Yes, you can. Click on the x to the right of any such news item in your feed (it appears when you hover over that item), and choose "Hide [page name]".

This way you retain the "like" status (i.e. continue to be a fan, as it used to be called), but you won't get any more updates from them in your feed.

If you ever want to undo this for some page, you can do that in your news feed options: scroll down to the bottom of your news feed and click "Edit options" (Facebook FAQ item on this).
