Introducing to you, Facebook's new way of selling you out!
I really would of liked an option to disable this somewhere in the privacy settings. Really, I would. Because I have no interest in this crap.
"Update your status about this event", "Share with everyone watching this event" and "This is a sample of what everyone watching is saying"? NO I DONT WANT TO!
But alas, I could not find an option, so here comes a heavy handed tactic to do so. Click on the AdBlockPlus icon and a dialog should appear.
