I don’t know who needs to hear this but be nice to fanfic authors. Reblog their stuff. Tell them you liked it. How you felt when reading. What school assignment you didn’t finish because of how captivating their story was. Don’t just scream to your friends about it. But tell them.
So many wonderfully talented people out there don’t get the praise they need. If their work brought you joy, make their day better by telling them it did.
Long ago I wrote a fic. Posted it under a different name without telling anyone in the fandom group I was active in. Watched how the online fandom group loved the fic and had a conversation of it in a positive spirit with each other - what did they like it, theories of this and that, how nice it was to get a new fic into this small fandom etc. - but did they leave feedback to the fic? No. I think it was only one person who commented the fic from the group.
I know the fan group liked the fic because I saw the outside comments. But, if I hadn’t seen them - like readers don’t - then I’d think the fic was not worth of my time and no one read it, or read it but didn’t care about it as it clearly was not worth of any comment.
We’re not telepathics. We don’t know. Tell the creators. They want it and appreciate the feedback. If we didn’t want you to interact with the stuff we create, like comment it/share it/reblog it/etc. we wouldn’t post the stuff online for you to see.
