StumbleUpon (Eye Candy)
For years, people have been using StumbleUpon to discover interesting Web content. But recently, the handy service launched a Facebook Timeline integration; so now, whenever you like a page, follow a new interest, channel, or use Stumbler, all your Facebook friends will know about it.
Want to get in on this "frictionless sharing?" Just go to your StumbleUpon settings page, and either connect your account to Facebook or select add my activity to Facebook Timeline.
