Obviously, she's a hottie. And she likes to pose all sexy like. EXAMPLE:
Of course, there are some internet types that doubt her place in the geek-o-verse. In a facebook comment thread from earlier this year, Liz herself addressed this issue nicely, ending with, "I didn't get the memo that once I grew into myself I couldn't still be myself..."
Thank you, Liz, for standing up for all us ladies who love our comic/game/book/movie collections as much as we love our butts :)
