These days, Facebook and Fake News are synonymous. I get Wikipedia’s stringent rules for what is or isn’t legit. If the almighty wiki overlords sanction a button to rid the world of disinformation, then bring it. Question is, where will it go? Facebook is riddled with tap-traps. Try tapping a pic and instead you’ve opened pandora’s box of pop-ups. Tags, filters, emojis — everything but the kitchen sink.
Adding Wikipedia to the FB clutter grenade without pulling the pin will take focus. And that’s a problem. Focus is the one thing Facebook doesn’t have.
