I, and about 12 million other folks, play a game called World of Warcraft. I also use facebook several hours a week to chat and keep in touch with friends. I think increasingly these "virtual" places are becoming true "third spaces." In fact there was a recent article about Warcraft fitting that bill quite nicely for some folks - http://news.cnet.com/8301-13846_3-10161861-62.html. Our culture is very cynical when it comes to new relationships. Increasingly, teens (and some adults) isolate themselves by immersion in these virtual places. Games and social networks are "safe" enough that they can sometimes drop the act and engage on a level of honesty that they might not engage in face-to-face. I've actually had long conversations with teens about their relationships with their fathers, problems at school, relationship blowups, and so on, and have been able to share Christ by doing so, all without ever meeting any one of them. It's a very fertile mission field.
