Betty WhiteA few years ago more than 500,000 fans of comedienne Betty White started a grassroots campaign on Facebook calling for her to appear on the late night television program Saturday Night Live. It worked. Ms. White was soon booked to host the May 9, 2010 show. After thanking Facebook users for their support in her opening monologue, she said “I didn’t know what Facebook was! And now that I do know what it is, I have to say, it sounds like a huge waste of time!”
