SFGate.com has an interesting article about Anime Expo and anime/manga fandom in general:
While the rest of the nation prepared to mark the Fourth of July by consuming charred lumps of meat and blowing stuff up, a gleeful mob was descending on unsuspecting Anaheim, Calif., for a very different kind of celebration. Called AX, or simply "the Expo" by its organizers and its legion of eager attendees, it too commemorated a declaration of independence . . . in this case, from the dull shackles of reality.
Breach the glass-and-concrete bunker of the Anaheim Convention Center on Expo weekend, and you pass into a parallel dimension populated by pink-haired schoolgirls and DIY 'droids, portly alien invaders and bespectacled ninja assassins. It's a place where little things like race and gender and nationality take a backseat to more important distinctions, like whether you prefer dubs or subtitles. A world where an ordinary guy can be a hero, a king -- or hell, a magical fairy princess. [SFGate.com]
