Apparently I have a growing fascination with what I will call "the blur", where virtual worlds collide with the real. Part of that fascination is how we will behave as human beings in these worlds. I consider human nature to be pretty dark, so I'm pretty sure all sorts of interesting psychological ramifications, few of them good, will arise as people hide their identities, cheat on their spouses, claim sin as not sin as long as it is virtual, etc... I see a growing field of study here that will touch upon multiple disciplines.
And along those lines, here is an article from wired that deals with the fact that relationships are relationships, even if they are "virtual", and those relationships affect our actions in the real world.
