The former Portuguese minister of education prof. Roberto Carneiro is one of the interviewed persons in this video: http://www.icwe.net/oeb_special/video_oeb2007.php
I think he is right pointing out that e-learning is about social networking, and therefore a challenge of dialogue between people. This years Online Educa gathered 2126 participants from 95 countries, of course real dialogues will be restricted to a few people and still informal dialogues between sessions was probably the most valuable. Dialogues in depth using technology is still a great challenge.
