I've told my family and they're fine with it, they even think it's interesting. I also told an online friend and she thought it was interesting, I mentioned it to another internet friend and he'd actually tried it before and wanted to try it again.
One time though, I told this group of people I sometimes talk to online and their reactions were basically:
Person one: "I've heard of it, sounds tiring"
Person two: "Yeah but it's for people with boring lives"
Person three: "Why not just do drugs?"
