Being able to hide a Facebook update after it posts isn't entirely new, but the social network is testing a way to let users keep things from ever hitting their Timeline. A "Hide From Your Timeline" checkbox will allow you to only publish something in the News Feed, without the need to remove it afterwards. CNET reports that any post you keep off your Timeline will still show up in search results and they'll be listed alongside your other activity on the "Your Posts" page that only you can view. The feature appears to available for a select few on the web, and Facebook isn't saying when or if it'll be a permanent addition.
