"wikipedia meets hypertext"
Check this out vis-a-vis autonomous self-directed learning (warning: may cause catatonic reverie as mind grapples with ramifications for learning & teaching):
The web as we know it was invented by a British academic working in Switzerland. Is a Nordic academic working in Britain about to redefine it forever?
Frode Hegland, a researcher at University College London, wants to change the basic structure of information on the net.
Hegland's project, Liquid Information, is kinda like Wikipedia meets hypertext. In Hegland's web, all documents are editable, and every word is a potential hyperlink....
...Liquid Information takes Berners-Lee's ideas and runs with them. Hegland's experimental system is geared toward allowing users -- not just writers and editors -- to make connections. Instead of just viewing websites, readers can change the way information is presented, or relate it to other information elsewhere on the web.
