I bet there'll be this whole new "generation" of Narnia fans, keeping the fandom alive. After all, the books were written in the fifties and yet here we are fanning it up. So when we're all... older... there'll be all these ~new~ fans in their teens and twenties. What will they squee over though? Old books, and by then even the movies will be old! They'll be crushing on a fourty-something cast who are young in the films. EHHH. It's weird, I DON'T WANT TO THINK ABOUT IT EITHER. (But it would be better that way than to have Narnia fandom just... just die. and have all these comms with ancient material and inactive users and dust and AAAHHH.)
But if we still are in fandom then, then we'll be ~Old School. How shall we put up with the n00bs? There'll be like two groups of fans: Old and New.

LJ better last, because when I die I want my grandkids to have my password and go read the embarrassing things I wrote way before they were born. I think about this kind of stuff all the time, UGHUGHUGHGUHUGH. :B
