Explore the possibilities of social networking features by expanding the user profile page:

• add user tags that describe interests etc, as links to "interest pages" eg constructivism
• interest pages that contain information about all the people who share that interest, as well as blog entries that use that tag, google searches, other info using standard Moodle blocks etc
• allow users to add other users as "friends", which are displayed on their user profile pages
• think about controls to prevent abuse of these features in a school environment.
• allow users to specify an external RSS feed to their own external blog, parsing the feed insert entries (optionally selecting by tag) as internal blog entries for that user, adding new tags/permissions as specified, with links back to external entry etc.
• if time, explore deeper integrations with Youtube, Flickr, MySpace, Facebook, Elgg etc.
