But I am also interested in getting something up on tinkeriDOTng too - something about tinkering - maybe a Github for inventions.
Checkout https://news.ycombinator.com/item?id=47967800 (DripStack) it is actually designed primarily for agents querying human writers - although on the front-end, humans can definitely query too. That concerns pre-release funding for financial writers.. wait how are humans writing these days? Who's to know how much slop it will return?
Regarding pre-release funding, I was thinking artist/creators might want to setup a mini-portfolio of content on the site, but then use the site as a "pipeline of ideas" with each seeking funding.
One use-case for Pieces are DJ playlists. I've seen DJs on Soundcloud wait until a mix gets a certain number of likes or reposts before they post the tracklist. You could contact DJs directly and tell them about the site.
