"Christina" is one of the most elegantly simple melodies in jazz, as well as acertifiable standard from bassist Buster Williams, who mentored Blackout members Stefon Harris and Casey Benjamin.
Jobs was acertifiable game-changer in the way that Bird, Johnson and Carroll certainly were, and his achievements will inform the hiring and pay decisions of professional team GMs and college athletic directors as they consider compensation for persons hired.
The same concept applies to online education: consumers are willing to pay much more for media that provides certifiable education than they pay for a Netflix movie.
Like the course offerings at most continuing education departments and university extensions: tastes of the real stuff, a window into the real thing, but nothing that made deep, holistic, and certifiable sense.
