Having a partner who games, even just recreationally from across the world, and is the opposite gender just kind of turns it in to a date-like experience over something you both really enjoy doing. Though it isn't a date unless otherwise established, I think that's why it's so sought after. On top of that, you can act out your feelings and curiosity for another gender over a headset far easier than you can in person, so it takes the pressure out of the social interaction at a young age (which I'm presuming is the case with "girl gamer etiquette"). Just play the game to play the game. If you meet a gamer, who you really liked playing the game with, and who [i]happens to be female[/i], then so be it.
