Pretty clear how I feel on the subject. ;)

Nicely said, Jules. Sums up everything I'd say about fic, save one.

I write fanfic because I fell in love with someone else's world. To me, there's no higher praise for another writer than to love her/his characters so much you cannot stop thinking about them.

So. If I'm ever good enough that someone gets the urge to fic my worlds? I'll cry for joy.
