I decided to put Bill O'Reilly and Stephen R. Covey to my twitter feed.  I decided to add Bill O'Reilly to my twitter feed because he is an expert on news both political and social.  He has his own news program on FOX News channel and is the most popular news pundit for conservative Americans.  His show has run for many years and I believe he has tried to keep as fair and balanced view on the news. Well, as much as a pundit on FOX can, but nonetheless he is a good reporter.  He has also written a number of books on politics and culture in America.
I chose Stephen R. Covey for a different reason.  I like books like "How to win Friends and Influence People."  They really speak to me.  Stephen Covey has written a number of successful books on how a person can improve themselves and make a difference, just like Dale Carnegie.  His most popular book is "7 Habits of Highly Effective People."
