If you're looking for a guinea pig community to test anything with, Scholar & Scribe has long been eager to create something like this. There's a regular stream of fiction coming into the community that could very well use some categorization, better sorting, a way for a mod account to "tag" things with small upvotes, etc.

You'll see some regular "feature" posts and contests, all which would be well-served by a nicer, custom frontend way of presenting them. We also have a pair of L2 tokens in the mix, but as stated managing those economies are a separate challenge, haha.

We used a breakaway a few years ago but never got far with it.
