Good article from Otaku USA last year. Good points. I have noticed similar things. Even with 'geek culture' more mainstream than ever, anime and manga fandom still seems to be more marginalized, even among American geeks. It's not as bad as it was 20 years ago, but the difference is still tangible.
kz(livetune) is a fantastic Hatsune Miku music creator. I hope that if our civilization ended, Miku could survive as proof that we were once a people that had technology to bring the music in our souls to life.
