Voice chat exists . Skype or T3.
Though I knew a guy that was so into trying to be a girl online he found voice modulation software to make him sound like a girl over Skype and t3, I assume most won't go to those lengths. Otherwise video chat Skype with them.
I know a few people, one being one of my best friends, who found his fiance in game, and they live together now rl.
There's many people here that wouldn't mind finding someone, I think because we as gamers are much more similar and comfortable with each other than we are IRL trying to find someone.
