I've thought about starting a otaku blog pretending to be a guy. I guess I would want to pretend to be a guy so I wouldn't stand out or something and so I could keep my professional "real" life seperate. But it would be too much of a bother to juggle some stupid "secret identity". Besides, I would get way more unwanted attention and drama being found out to be a girl then I would just saying I was a girl in the first place.
