I think there’s different demographics for who is creating and who is reading. There was a 90s kids thread a few weeks ago and a lot of the creators (on the forum, at least) seem to be between the ages 20 & 35. There’s obviously going to be plenty both older and younger. As for readers, (and I’m just referring to non-creator readers atm for the sake of simplicity, I do think they err a bit younger, more toward 15 and up. That’s just been from what I’ve seen so I could be way off, honestly.
