When you want to softly steer people into an option, do you place the preferred button left or right to the other one?
More Details Specifically it is about registering with a Facebook account, or with a custom 'local' account. We think our product is better by providing Facebook features, but for logical reasons people are hesitant to register with their FB account. So we provide both options, with explanations.
