I have started a collection of "tiddler" notes at http://curl.tiddlyspace.com using their variant of TiddlyWiki, the one page wiki.
On the server-side, these wikis tend to be PHP or Python, but on the client-side they are a tangle of JavaScript and CSS in a single portable HTML file.
So naturally I cannot help but wonder what a TiddlyWiki could offer as a Curl page. For "plugins" we might use Curl's dynamic package loading.
Many TiddlyWiki implementations are curently hampered on browsers built with WebKit in that the TW page must be accompanied by a tiny Java JAR file to permit updates to the server.
I will try to find a moment to put up a post on a TW using Curl OCC (Occasionally-connected Computing.)
A useful TW is the d-cubed variant for GTD which you can see at my http://aule‑pages.tiddlyspot.com
