Sergio Appears On The Blog At Last!

Sergio is an engineering student at the University of Denver and has worked at the DU Bookstore since September.  He agreed to be featured on my Blog after being persuaded to do so by a number of other Bookstore employees.  I am of course very flattered that these employees spoke so highly of my Blog and told Sergio what an honor it is for him to appear on it.  However, I couldn't help but notice that most of the employees extolling my Blog refuse to appear on it themselves.  What's up with that?
