It's a pity it was mentioned so briefly in passing. From what I have read, Alex Jones has a monthly listenership of about 6 million people? How many people will have likely heard that brief sentence by watching this interview?

Any individual only has to hear about the same thing three times in a relatively short time frame, before they take note. So getting the word "Steemit" out there in front of millions of people is powerful, if a few of them hear the word once or twice elsewhere as well.
