So, I'm not super up on this canon, but as far as I can tell, your Haurhi is pretty much perfect, having that perfect mix of kindness, obliviousness, and sarcasm. She's really great.

On the other side, I have a hard time noticing other people's tagging activity, but you do seem to tag her more with her castmates than anything. Get her out there a bit more? Unless I am also oblivious about her tags.
