Perchance
I think this is neat–a language for creating text generators, and a site that hosts them.
It has different affordances than Tracery: it cares a bit more about text and lists, has built-in notation for adjusting weighting, a little more state to remember generated things, and has first-class support for pulling in content from other generators. Having more domain-specific languages for generating things helps give us insights into what the space of possible generators looks like and can help suggest new places to look.
