I always feel bad that I can’t quote everyone I speak with, and often apologize when I text them the story link.
But journalism usually requires speaking with way more people than you can quote to make sure you have the story RIGHT. You may only have space to quote 3 people, but you should never only speak to three people for an article.
I can't believe I need to say this, but if, as a journalist, you use my time, research & expertise without quoting me, don't be surprised if I never return your call.
