I agree that it would be boring to watch Naruto going through paperwork, assigning missions, etc., but I've read a few fanfics where Naruto is Hokage and they were really interesting. Masashi-san just needs to hire a few Naruto fans that write fanfics to come up with ideas for him. ;P XD
(Not at all. ^^ I prefer to call him "Masashi-san" since sama is too polite and it's usually said by restaurant waitresses, hotel staff, etc. to customers.)
