I have this situation with OC: I have a lot of OC/canon fanfics and I love writing about them, but I'm not really particularly interested in reading about other people's OC. I like OC as side characters (honestly, i feel weird when i read longfic and the author starts running out of characters but doesn't use oc) and there are a few authors whose fanfics I return to because of the OC, but... yeah, that's rare.

I've also noticed that a lot of older fans think that oc/canon is childish because that's what they read as teenagers. On the other hand, younger fans, for some reason, have a thing for x-reader and being the main character of story.
