Publisher’s Weekly scored an interview with mangaka SHIMOKU Kio, the creator of Genshiken. Its a pretty good interview (too bad Shimoku-sensei’s question wasn’t answered back for the publication) so if you were a fan of the manga or wonder what Shimoku-sensei’s thoughts are about otaku, I encourage you to read the article.
Update (30-Oct-2016): The article no longer exists, BUT the link below is to the archived version on the Way Back archive.
