Since a new version has been released 4 days ago, let me take the opportunity to mention that @FeatherWiki is still the best, single-page local wiki ever made. It's minimalistic, extensible, and accessible to #screenReader software as well.

If you like TiddlyWiki but find yourself confused because of the myriads of expanding sections, you will love FeatherWiki.
