Jump in. Worst that happens is it'll languish at 1 vote. I had some of those.

I'd forgotten about some of those early constrained writing prompts I'd done until I requested my data. I got a laugh out of them now. Now much traction then. Problem is that I can't do anything with them. Even if I made a book of prompts, people care about the story in the finish product, not "hey, look at this crazy story that doesn't repeat a word or use the word 'the'!"
