I sometimes have ideas for what I think might be compelling stories - most would fall in the category of fantasy/science fiction; however, I realise that I have no real interest in telling stories. I write good prose and explain well, but I tend to write about technical matters, generally speaking, and if I set out to write a story, I quickly get bored and start thinking about the logical/technical/scientific aspects instead. Is there a 'market' for story ideas? I don't mean in a commercial sense, all I'd want is a kind mention in the forewords or something, but something like a forum where I can offload my ideas and the real writers could browse around and discuss?
The closest thing I can think of to what you're describing is writing prompts. They're short (maybe 40-50 words) and provide the seed of an idea, essentially just a premise that a writer can take as a starting point to create a story from.
For examples of what I mean (and potentially even a place to post your own) there's a SubReddit here
