I want to hear in their own terms, because I genuinely don't know if I can understand the idea in terms of my own experience. I can make it make sense to me, sure; anyone can do that with almost anything. I don't have a guide to how closely that would correspond to the sense made of it by the people who actually pursue it. Third-party opinions don't actually count for much there, but this might also be too new a thing to have been studied.
I don't know. It seems to me like it would have to be terribly lonely and unfulfilling. But that might just be in comparison with my own pre-Internet experience, or maybe something I'm entirely missing.
