Imagine 15 years ago as a practicing lawyer taking 30 minutes in the morning to skim news headlines from 400 or 500 reliable news sources you selected because they offered news and commentary related to your work as well as monitoring keywords relevant to your area of law (clients' names, subjects, cases, and the like) for their use in the news and private commentary.
Then in the same 30 minutes you instantaneously shared 10 or 12 of those headlines, with a very short comment, with 1,000 people who looked as you as a reliable authority in your niche. The people you shared the headlines with included clients, prospective clients, referral sources, and their influencers (reporters, publishers, conference coordinators, civic leaders, association leaders, and the like).
