So what's the icon going to be, a flat hand shaking?
We can only speculate what the button would look like. Our feeble minds cannot comprehend that which Facebook must go through in making such an important decision. We are sure it involves lots of ritualistic wailing and great gnashing of teeth that goes on for weeks or possibly eternities. Personally we'd like to see a button with a faceless grey man slightly shrugging with his head tilted 10 degrees to the left. But that's just our opinion.
