Does sitting by a nice cozy fire, with a cup of hot tea/chocolate, and a book you can read for hours even when your eyes grow red and dry and you look sort of scary sitting there with your insomniac appearance? Then you fit this category perfectly! You love the power of the written word and its eloquence; and you may like to read/write poetry or novels. You contribute to the smart people of today's society, however you can probably be overly-critical of works.
I'm definitely also a grammar nerd: I corrected the improper use of an apostrophe up there. ("It's/its" is actually a really easy rule to remember! Want me to tell you?)

I'd also move up Artistic Nerd up a couple of lines; I'm really more of that kind of nerd than I'd be a Gaming/Computer Nerd or an Anime Nerd...
Oh oh oh, and I'm definitely a music nerd, but the test isn't set up in a way that differentiates between being that and being a musician nerd, and I'm not a musician nerd...
