The whole point of having a kink meme is that there are some things you can't or don't want to write yourself. I am already participating by writing fills for other people who don't want to write their own prompts. It's not a crime to not want to just read your own writing all the time. Like I get what you're saying 'build a niche' but a) femslash shouldn't have to be considered a niche and b) I am busy not just with writing but with life.

Everything on meme and ao3 is just starting to look really same-y and I see people saying 'there's nothing left to write' when they are just writing the same two pairings and the same four topics ad nauseum.
