Two of my close friends are quite interested, one of them doesn't really want to try it out herself though. Another friend is kind of worried that I lose my grip on reality and start living in a dream world (i.e. stop caring about the real world). I can imagine though that some other friends of mine would label it "crazy" too...
I've also told my parents what I'm doing, but neither did they seem very interested nor bothered by it. They kind of just accept it as something I find cool.
