TiddlySpace lets users organize their thoughts and ideas so that they are available wherever, whenever, and however they're needed. A tiddler is a chunk of content created on TiddlySpace that comes with its own URI for easy sharing. Users can organize their tiddlers by tagging and linking to them. A simple model for sharing, distributing, and adapting content makes collaboration easy. Developers can customize, integrate, and extend TiddlySpace by using its extensive RESTful APIs.
