"Crowdsourcing efforts don’t fit neatly into discrete classification, but for the purpose of this report, we’ve organized our typologies into six different calls to action: Voting—prioritizing which stories reporters should tackle; Witnessing—sharing what you saw during a news event; Sharing personal experiences—telling what you know about your life experience; Tapping specialized expertise—contributing data or unique knowledge; Completing a task—volunteering time or skills to help create a news story; Engaging audiences—joining in call-outs that can range from informative to playful [...] The research shows that crowdsourcing is credited with helping to create amazing acts of journalism. It has transformed newsgathering by introducing unprecedented opportunities for attracting sources with new voices and information, allowed news organizations to unlock stories that otherwise might not have surfaced, and created opportunities for news organizations to experiment with the possibilities of engagement just for the fun of it."
