The reddit thread is really good - a few interesting things are the Notch post (I think he's the mindcraft guy) is very bigger picture, and I kind of understood the poster who says its ruined now because he/she thought it should be to escape and get away from people and mixing it up with social media is just going to do the opposite. We have one at work and you really do feel like you're in a secret world where you can get up to all sorts, it's great.

Something that I found a bit scary is the idea that it can be used for mental health therapy like phobias and stuff, I can understand why people are creeped out by facebook getting their hands on it.
