I really did not care for it... I watch it occasionally when it comes on CN & I have read up to volume four, but I have not felt compelled to go any further. Of course I am a female, and the series is totally shonen... But that doesn't really say much since I like a lot of shonen, haha. I cannot really say why it doesn't appeal to me, but it could be the lack of relationships or pretty girls.
...Oh goodness, my nerd is leaking out. ):
