Domino is explicitly inspired by TiddlyWiki, though it’s kind of a different beast in practice. Decker isn’t, but the web edition self-propagates in much the same way. And I could swear Kartik Agaram used to experiment with a framework for creating apps like that, though I can’t find it on his website anymore.
P.S. To nitpick: Twine wasn’t merely inspired by TiddlyWiki. It was based on it!
