I describe my writing as thrillers with a tech edge, but I could equally refer to a geek edge.
I grew up watching SF on screen (Star Trek, Star Wars, ET, Gremlins etc) and that interest stayed with me, even as I moved into harder-edged stuff by Stephen King and Tom Clancy. I enjoy comic books that take their characters and worlds seriously (Watchmen and Dark Knight Returns seem to be the turning points in the medium), have played the odd computer game and enjoy classic rock music.
While my chosen genre is the thriller, that interest in techy/geeky topics has stayed with me, so you'll find hints of it coming through in the things my characters like, or the occasional name that's got a throwaway in-joke reference.
With that background, I find it both annoying and amusing the way that mainstream media treats geeky topics. While lots of recent hit movies have a comic book, computer game or SF background; while the new love interests in romance novels all seem to be vampires or werewolves; while the current hot topic on Twitter is a robot driving around on Mars; while computer gamers are now just as likely to be professional women than nerds in their parents' basement; while Peter Jackson appears to be planning his sixth Tolkien movie; lots of stories still find the opportunity to poke fun at the geeks that inhibit the core of this world.
But, really, most people are geeks - the issue is what they're geeky for.
