The document discusses examples of both positive and negative effects of digital footprints. Positively, teens used social media interactions to power a restored car to drive across the country and meet with officials, a cancer patient's song inspired many after being posted to YouTube, and a blog and petition led to a boycott of Abercrombie and Fitch. Negatively, a waitress was fired after blasting customers on Facebook, a juror was dismissed after posting details of her case online, and a cheerleader was fired when a photo of her at a party with offensive symbols surfaced on Facebook.
