I know a lot of us joke either publicly or amongst ourselves about 'bad fanfiction'. I freely admit I have complained about this very thing to my close friends, but I always feel guilty afterwards. You know why? 'Cause I think that's a pretty asshole'ish thing to laugh about.
I'd like to present to you the idea that, yes, there is fanfiction that is created by people with little writing experience. But hey, guess what? Each story that individual writes is more experience for them, and that is NOT something we should discourage!!
Lately I've seen a post going around on tumblr shaming 'bad' fanfiction, stating that their own dignity has been lowered because they resign themselves to reading badly written fanfiction just to get their fix of their (usually rare'ish) pairings.
I say, fuck that mentality. Let's replace that negativity with something positive!
Instead of complaining and moving on, why don't we contact that writer, leave them positive feedback and encourage them (ESPECIALLY if they're writing a rare pairing we love)? We don't have to be brutal about the quality; be enthusiastic and happy about finding the pairing or theme you enjoy! Explain how you love these characters/themes/pairings, and you're so happy to find someone else who does as well. If you can build up a good rapport with the author, you might even get the chance to bounce ideas back and forth, help them improve their writing, and help encourage even more of those characters/pairings to be created!
Sure, some authors may never respond. Maybe some wrote the fic only as a joke. Maybe some feelers you send out will be dead ends.
But isn't it worth a few initial moments of your time if even just one person responds? If even just one person is encouraged by kindness and kinship? If you make just one friend?
Be supportive of each other. Of other authors, artists, and fandoms. We all do this for fun, we spend our own free time to create and share, and that should never be ridiculed!
