I blogged before about TiddlyWiki the amazing selfcontained (HTML, CSS and JavaScript) wiki in a web page. I’ve now come across tiddlyspot where you can create a server based TiddlyWiki that can be private or public.
I’m convinced that between services like tiddlyspot, Ning.com, Blogger.com and Flckr.com you can create a robust distributed web presence without needing an ISP. Push your content out into the world.
