David Tosh's presentation: Computing Means Connecting (given at the "E-portfolio and pervasive computing" event hosted by the Knowledge Lab in Denmark.) gives us a peek into how integration and networking is occurring within the eportfolio space. Elements like Blogs, wikis, RSS, tagging, etc. - are networking and "speaking" to each other in platforms like Elgg -- " an open source learning landscape platform." It allow a user to create a "personal learning landscape with the goal of connecting learners, instructors and resources creating communities of learning."
Elgg also allows linking and drawing in of resources from other platforms.
Much of e-learning (or learning assisted with some technology) is moving towards social-networks. Platforms like Elgg that allow the integration of many of the new social-networking tools and technologies that allow building communities: FOAF, RSS/Atom, Blogging, etc. Such connection-based networks are finding increasing levels of adoption from users because they are largely informal and allow the users to build communities that aid their "learning" on their terms.
