I have written and researched! And I'm moving on apace, which is pleasing.

My fandoms are usually not so small that I'm influencing fanon just by writing a few fics. But I have been in one RPF fandom where, because of the giant and meandering nature of a canon that is basically reality, a lot of the fic we wrote was based on communally-created fanon instead.

On the other hand, right now I'm writing original fic. So what I'm writing right now is not just fanon, it's canon! Scary. But cool.
