The “who” in your Moment will depend on your topic and industry, of course, but you will want to be sure that you’re including important and relevant perspectives. You’ll also want to check and verify the credibility of the accounts behind the Tweets.
For example, if you’re creating a Moment around a sporting event or news in a league, you perhaps would want to include the reactions from athletes, commentators, and major news coverage. You might also consider fan reactions to round out the story. Or, if you’re a news outlet covering a local story, you might want to include your initial coverage of the story, as well as any additional information that emerges from your sources.
