Boss Engrossed in the Internet

My boss has become totally engrossed in the Internet.  WTF?  Are not the employees supposed to be the persons using the web to an extreme at work?

I don’t know what is going on here, but he will zone out seated at the computer on the sales floor surrounded by customers and then appear as if he is completely unaware of the customers presence.  It is rather amazing, the sheer focus with which he uses the net.  I, for one, have never really been able to concentrate like that on one particular activity.
