Joss on Buffy fanfic

Do you ever delve into the voluminous fan fiction around “Buffy”?

I have delved into it. There’s a bunch. There isn’t a better barometer of the kind of success that I crave, which is that people haven’t only enjoyed the work; they’ve internalized it. I don’t, obviously, spend all my days reading it because that would make me creepy, but it’s a huge, huge thing for me that people have taken it into their lives.
