Wouldn't the Anime&Manga board fit better under Entertainment?

I can understand both sides of the issue. On one hand, it is entertainment - on the other, those interested in it make a focus, much like a hobby would be (then again, so do gamers and that's under Entertainment).

So yeah, I'm thinking it would fit under Entertainment too.

(and for the creation aspect, I have posted a couple of announcements for AMVs I've made, but those are few and far between because I'd been too involved with making tracks for multi-editor projects like AMV Hell CE, or currently managing to scrape things up for AMV Hell 4)

I see it as a hobby since there is an aspect of Manga in which people draw in their free time.

No, I don't think so. Anime is too broad a term. What would you fit it under? Comics? Books? Television? Movies?

Besides, those who like anime also obsess over the Japanese culture. For some people, who like cosplay and the like and dye their hair the same colour as their favourite character, it's also practially a lifestyle. I think it fits rather well under hobbies, because it can't be categorised as simply anything else.
