There's a difference as I explained earlier. In a conventional company ownership structure, owning a share means you can vote on company matters, to elect directors to the board etc. However in the case of FB, the outsized voting powers of class B shares are not available to the public. In other words the shares have no inherent value. An investor might be wiser to invest in FB bonds since they are paid ahead of holders of equity should FB implode.
