Every geek girl has had a crush on Han Solo or Luke Skywalker. Most of us, both. Many of us still do, secretly. Episodes that explore a character's inner feelings are just as important, if not more so, than ones where they go around shooting things. Geek girls like Spock better than Kirk.
Geek girls stick together, and look for themselves in their entertainment.
They will pick up on the brainy computer whiz kid actually being a girl for a change. They will cheer when a woman becomes Chief of Engineering. If you know what's good for you, you will cheer, too. So you finally get to meet your geek girl in person. Most geek girls have low-maintenance appearances.
