As what exactly the Google +1 Button does continues to mystify some users , security researcher Ashkan Soltani and Brian Kennish, former Googler and the mind behind Facebook Disconnect , have decided to kill two buttons with one browser extension, creating Like +1 . Unlike the +Like extension , which allowed you to Facebook Like Google search results, Like +1 turns all offsite Like Buttons into hybrid Like+1 Buttons, allowing you to consolidate some of your social button clicking behavior into one click, so you can simultaneously +1 something while you also Like it.
