YouTube launched an online Journalism school of sorts for anyone wanting to learn how to be a reporter. The “YouTube Reporters Center” has tips from CBS Katie Couric, Washington Post’s Bob Woodward, and other top journalists, sharing their wisdom on what it takes to get a good story out or do a good interview. It’s a great idea – a repository of advice and lessons. It is a lot like VatorNews’s library of lessons and advice on how to be an entrepreneur. Do you want to be a great entrepreneur – make sure to watch our “Lessons Learned” channel and hear from the seasoned entrepreneurs.
