Character Names

[silchi.livejournal.com]

In all the time I've spent following Naruto, one thing has always baffled me: the way in which character names are written.

Let's take Naruto, for example - in the manga, and the series logo, his name is written in katakana. Yet in episode 50 something, when he signs the frog-summoning scroll, he writes his name in hiragana.

Also, think about Sakura's name - that's a Japanese word, definately not a foreign one, so why isn't it written in hiragana?

Just curious, is all. =)
