I think it's a good idea because a lot of the girls I have lined up don't talk about gaming that much, so letting them talk about gaming for my blog is something they're really down for. I have a girl who I only just found out plays videogames and she has pretty much every game I can think of, and there's another girl who absolutely adores Skyrim and would love the chance to be featured talking about it, and talking about her character on it and how many hours she's clocked because she loves it, and I think it's interesting - so why not do it? My blog is about gaming, and as much as I appreciate what you're saying, there still is sexism surrounding gaming. Games magazines are put with the porn mags in some supermarkets, I've been to game shops to buy a game and been asked if I was buying it for my 'boyfriend'.
I don't believe I'm perpetuating a stereotype at all by taking girls from all walks of life, from different careers (Skyrim girl works in architecture!) who just want to talk about how much they love a game, or gaming. And then if I can't do that, isn't that building to the stereotype again? Why do girls get criticised for wanting to talk about games? "Oh she just wants attention by talking about these games." Or, maybe she just wants to talk about something she's passionate about. I don't see how it's any different to running a feature on girls who knit, bake or are interested in fashion, imo.
